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.

2011-09-04 Aidan Kehoe <kehoea@parhasard.net>
* bytecomp.el (byte-compile-output-file-form):
* bytecomp.el (byte-compile-output-docform):
Bind print-circle, print-continuous-numbering in these functions,
now those variables are available.
* lisp.el (forward-sexp):
* lisp.el (backward-sexp):
Recognise leading #N= as being part of an expression.

* automated/lisp-reader-tests.el:
* automated/lisp-tests.el (literal-with-uninterned):
* automated/symbol-tests.el (foo):
Test print-circle, for printing (mutually-)recursive and circular
structures.
Bind print-continuous-numbering where appropriate.

I would like to ;; delete it, but it serves as a useful reminder as to how things used to ;; work. ;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ;; Special formatting conventions are used in this file! ;; a backslash-newline is used at the beginning of a documentation string ;; when that string should be stored in the file lib-src/DOCnnn, not in core. ;; Such strings read into Lisp as numbers (during the pure-loading phase). ;; But you must obey certain rules to make sure the string is understood ;; and goes into lib-src/DOCnnn properly. Otherwise, the string will not go ;; anywhere! ;; The doc string must appear in the standard place in a call to ;; defun, autoload, defvar or defconst. No Lisp macros are recognized. ;; The open-paren starting the definition must appear in column 0. ;; In defvar and defconst, there is an additional rule: ;; The double-quote that starts the string must be on the same ;; line as the defvar or defconst. ;; !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ;; ********************************************************************** ;; You should never need to write autoloads by hand and put them here. ;; It is no longer necessary. Instead use autoload.el to maintain them ;; for you. Just insert ";;;###autoload" before defuns or defmacros you ;; want to be autoloaded, or other forms you want copied into loaddefs.el ;; (defvars, key definitions, etc.). For example, ;; ;;;###autoload ;; (defun foobar () ....) ;; ;;;###autoload (define-key global-map "f" 'foobar) ;; ;;;###autoload ;; (defvar foobar-var nil "\ ;; This is foobar-var's doc-string.") ;; Then do M-x update-file-autoloads on the file to update loaddefs.el. ;; You can also use M-x update-directory-autoloads to update the autoloads ;; in loaddefs.el for all .el files in the lisp/ directory, or M-x ;; update-autoloads-here to update the autoloads for each file that ;; already has an autoload section in this file. ;; ********************************************************************** ;;; Code: ;; These variables are used by autoloadable packages. ;; They are defined here so that they do not get overridden ;; by the loading of those packages. ;; Names in directory that end in one of these ;; are ignored in completion, ;; making it more likely you will get a unique match. (setq completion-ignored-extensions ;; this is way way way bogus. ;; completely wtf? ;; the only things that should be here are those that are ;; (a) universally recognizable, and ;; (b) obvious backup files, or ;; (c) obvious binary files that are generated on a ;; PER-SOURCE-FILE basis, so that they will actually ;; cause annoyance.
