If the position of a window's cached point is deleted, use buffer point instead
src/ChangeLog addition:
2014-06-17 Aidan Kehoe <kehoea@parhasard.net>
* extents.h:
* window.c:
* window.c (unshow_buffer):
* window.c (Fset_window_buffer):
Use extents, rather than markers, for the window buffer point
cache, so that when the text containing that window buffer point
is deleted, the window display code uses the buffer's actual point
instead of the position that the marker had been moved to.
Fixes Michael Heinrich's problem of
http://mid.gmane.org/6zr42uxtf5.fsf@elektra.science-computing.de ,
introduced by Ben's patch of
https://bitbucket.org/xemacs/xemacs/commits/047d37eb70d70f43803 .

| 996 | 17 This directory contains a number of XEmacs dynamic modules. These |
| 18 modules can be loaded directly with the command 'M-x load-module'. | |
| 19 However, the preferred method of loading a module is to issue a | |
| 20 "(require 'module-name)" command to the Lisp interpreter. This will | |
| 21 store information so that a later "(unload-feature 'module-name)" can | |
| 22 succeed. | |
| 388 | 23 |
| 996 | 24 To compile one of these modules, simply enter the desired directory, |
| 25 type 'configure', and then 'make'. If you are building the module for | |
| 26 an installed XEmacs, then 'make install' will place the module in the | |
| 27 appropriate directory for XEmacs to find it later (assuming you have | |
| 28 permission to write to that directory). A subsequent 'load-module' or | |
| 29 'require' will then load the module, as described above. | |
| 388 | 30 |
| 996 | 31 Each of these demonstrates different features and limitations of the |
| 32 XEmacs module loading technology. For a complete discussion on XEmacs | |
| 33 dynamic modules, please consult the XEmacs Module Writers Guide, which | |
| 34 can be found in the ../info directory. | |
| 388 | 35 |
| 996 | 36 For those wanting to get started with module writing, please see the |
| 37 'sample' directory. It contains two subdirectories: internal and | |
| 38 external. The 'internal' subdirectory contains the framework needed to | |
| 39 migrate some core piece of XEmacs functionality into code that can | |
| 40 either be compiled into the core or built as a separate module. The | |
| 41 'external' subdirectory contains the somewhat simpler framework needed | |
| 42 to build a module separately from XEmacs. These should be considered | |
| 43 starting places for module writing. |
