Implement print-circle, printing circular structures in a readable
fashion, and treating them appropriately on read. This is by means
of two new object methods, print_preprocess (detecting
circularities), and nsubst_structures_descend (replacing
placeholders with the read objects).
Expose the substitution to Lisp via #'nsubst and its new
:descend-structures keyword.
Store information as to whether symbols are interned in obarray or
not in their header, making checking for keywords and uninterned
symbols (and thus printing) cheaper.
Default print_gensym to t, as Common Lisp does, and as a
more-than-decade old comment suggests.

| 35 -- A time line for Lucid Emacs/XEmacs is | |
| 36 | |
| 2517 | 37 Version 19.0 shipped with Energize 1.0, April 1992. |
| 38 Version 19.1 released June 4, 1992. | |
| 39 Version 19.2 released June 19, 1992. | |
| 40 Version 19.3 released September 9, 1992. | |
| 41 Version 19.4 released January 21, 1993. | |
| 42 Version 19.5 released February 5, 1993. This was a repackaging of 19.4 with a | |
| 43 few bug fixes and shipped with Energize 2.0. It was a trade-show giveaway | |
| 44 and never released to the net. | |
| 45 Version 19.6 released April 9, 1993. | |
| 46 Version 19.7 was a repackaging of 19.6 with a few bug fixes and | |
| 442 | 47 shipped with Energize 2.1. Never released to the net. |
| 2517 | 48 Version 19.8 released September 6, 1993. (Epoch merger, preliminary I18N |
| 49 support) | |
| 50 Version 19.9 released January 12, 1994. (Scrollbars, Athena.) | |
| 51 Version 19.10 released May 27, 1994. Known as "Lucid Emacs" when | |
| 52 shipped by Lucid, and as "XEmacs" when shipped by Sun; but Lucid | |
| 53 went out of business a few days later and it's unclear very many | |
| 54 copies of 19.10 were released by Lucid. (Last release by Jamie Zawinski.) | |
| 55 Version 19.11 (first XEmacs) released September 13, 1994. | |
| 56 Version 19.12 released June 23, 1995. | |
| 57 Version 19.13 released September 1, 1995. | |
| 58 Version 19.14 released June 23, 1996. | |
| 59 Version 20.0 released February 9, 1997. | |
| 60 Version 19.15 released March 28, 1997. | |
| 61 Version 20.1 (not released to the net) April 15, 1997. | |
| 62 Version 20.2 released May 16, 1997. | |
| 63 Version 19.16 released October 31, 1997; retiring of v19 series. | |
| 64 Version 20.3 (the first stable version of XEmacs 20.x) released November 30, | |
| 65 1997. | |
| 66 Version 20.4 released February 28, 1998. (Jamie claims this version is the | |
| 67 "first reasonably stable release with MULE support" and says that "XEmacs | |
| 68 'core' and 'packages' now packaged separately.") | |
| 69 Version 21.0-pre5 released July 18, 1998. (Jamie says "Numbering scheme goes | |
| 70 wonky due to switch to stable + unstable branches.") | |
| 71 Version 21.0.60 released December 10, 1998. (The version naming scheme was | |
| 72 changed at this point: [a] the second version number is odd for stable | |
| 73 versions, even for beta versions; [b] a third version number is added, | |
| 74 replacing the "beta xxx" ending for beta versions and allowing for | |
| 75 periodic maintenance releases for stable versions. Therefore, 21.0 was | |
| 76 never "officially" released; similarly for 21.2, etc.) | |
| 77 Version 21.0.61 released January 4, 1999. | |
| 78 Version 21.0.63 released February 3, 1999. | |
| 79 Version 21.0.64 released March 1, 1999. | |
| 80 Version 21.0.65 released March 5, 1999. | |
| 81 Version 21.0.66 released March 12, 1999. | |
| 82 Version 21.0.67 released March 25, 1999. | |
| 83 Version 21.1.2 released May 14, 1999; on comp.emacs, May 28. (This is | |
| 788 | 84 the followup to 21.0.67. The second version number was bumped to indicate |
| 85 the beginning of the "stable" series.) | |
| 2517 | 86 Version 21.1.3 released June 26, 1999. |
| 87 Version 21.1.4 released July 8, 1999. | |
| 88 Version 21.1.6 released August 14, 1999. (There was no 21.1.5.) | |

| 3120 all the out of date dumped lisp. It will execute both of the main_1 | |
| 3121 calls and the second one must not touch the first computation because | |
| 3122 argc/argv are hosed the second time through. | |
| 3123 | |
| 3124 xemacs -- Only the second main_1 is executed. The invocation path must | |
| 3125 computed but this only matters when running in place or when running | |
| 3126 as a login shell. | |
| 3127 | |
| 3128 As a bonus for straightening this out, XEmacs can now be run in place | |
| 3129 as a login shell. This never used to work. | |
| 3130 | |
| 3131 As another bonus, we can now guarantee that | |
| 3132 (concat invocation-directory invocation-name) contains the filename | |

| 3802 up MS Dev Studio and start debugging the application -- similar to | |
| 3803 producing a core dump and then going back with a debugger to investigate | |
| 3804 the core dump, except that the program is still running. When this is | |
| 3805 installed, it's better not to "pause so user gets messages" because the | |
| 3806 debugger will pause anyway; and in case we're currently with a menu | |
| 3807 popped up or somewhere else inside of an internal modal loop, we will | |
| 3808 get wedged when we output the "pause". (It seems that the two modal | |
| 3809 loops will fight each other and the return key will never be passed to | |
| 3810 the "pause" handler so that XEmacs's GPF handler can return, resignal | |
| 3811 the GPF, and properly go into the debugger.) */ | |

| 3954 The line above is original. Unfortunately, when an error is tripped | |
| 3955 inside of the handler (e.g. during Fbacktrace()), and the handler for | |
| 3956 the handler is invoked, it correctly notices that something is amiss | |
| 3957 and it should just return -- but it returns EXCEPTION_CONTINUE_SEARCH, | |
| 3958 which causes the debugger to be invoked debugging the handler code in | |
| 3959 this function -- and WITH THE STACK UNWOUND so that you see main() | |
| 3960 calling mswindows_handle_hardware_exceptions(), calling Fbacktrace(), | |
| 3961 and a crash a couple of frames in -- AND NO SIGN OF THE ORIGINAL CRASH! | |
| 3962 | |
| 3963 There's some real weirdness going on in the stack handling -- unlike | |
| 3964 in Unix, where further crashes just keep adding to the stack, it seems | |
| 3965 that under the structured-exception-handling, the stack can actually | |
| 3966 bounce back and forth between the full stack at the location of the | |
| 3967 exception and the unwound stack at the place where the __try clause was | |
| 3968 established. I don't completely understand it. What I do know is that | |
| 3969 returning EXCEPTION_EXECUTE_HANDLER on nested crash has the effect of | |
| 3970 aborting execution of the handler and going back to the outer filter | |
| 3971 function, which returns EXCEPTION_CONTINUE_SEARCH and everything is | |
| 3972 hunky-dorey -- your debugger sees a crash at the right location with | |
| 3973 the right stack. | |
| 3974 | |
| 3975 I'm leaving in the trickier Unix-like code in the handler; someone who | |
| 3976 understands better than me how the stack works in these handlers could | |
| 3977 fix it up more. As it is, it works pretty well, so I'm not likely to | |
| 3978 touch it more. --ben | |
