syntax-table fixes
1. the updating of mirror tables every time a syntax table was modified
was taking up huge amounts of time so i added a dirty flag and made the
updating "just-in-time".
2. no-longer-used char-table-entries were not getting "freed", generating
tons of garbage.
3. syntax_match() was being incorrectly called on mirror tables in the
cache, not the original syntax table.
buffer.c, syntax.c: Move syntax table description from buffer.c to syntax.c.
chartab.c, chartab.h: Free extra char table entries to avoid excessive garbage.
Add flags for dirty and mirror_table_p to char tables.
Add a back pointer from mirror tables to the original syntax table.
When modifying a syntax table, don't update the mirror table right
away, just mark as dirty.
Add various asserts to make sure we are dealing with the right type
of table (mirror or non-mirror).
font-lock.c, syntax.c, syntax.h: Add entry to syntax caches for the non-mirror table. Set it
appropriately when initializing the syntax table. Use it, not
the mirror table, for calls to syntax_match().
Don't create a bogus float each time, just once at startup.
Add some asserts, as in chartab.c.
syntax.h: When retrieving the syntax code, check the dirty flag and update
the mirror tables as appropriate.
Add some asserts, as above.

-*- Text -*- This is the file .../info/dir, which contains the topmost node of the Info hierarchy. The first time you invoke Info you start off looking at that node, which is (dir)Top. Rather than adding new nodes to this directory (and this file) it is a better idea to put them in a site-local directory, and then configure info to search in that directory as well. That way, you won't have to re-edit this file when a new release of the editor comes out. For example, you could add this code to .../lisp/site-start.el, which is loaded before ~/.emacs each time the editor starts up: ;; find local info nodes (setq Info-directory-list (append Info-directory-list '("/private/info/"))) Then, when you enter info, a dir file like this one will be automatically created and saved (provided you have write access to the directory). The contents of that file "/private/info/dir" will be appended to the contents of this file. File: dir Node: Top This is the top of the INFO tree This is Info, the online documentation browsing system.
