Provide `char-code-limit', implement the GNU equivalent in terms of it.
src/ChangeLog addition:
2015-03-15 Aidan Kehoe <kehoea@parhasard.net>
* text.h: Make CHAR_CODE_LIMIT available as a #define.
* text.h (valid_ichar_p): Use it.
* text.c: Make a fixnum Vchar_code_limit available here.
* text.c (non_ascii_valid_ichar_p): Use CHAR_CODE_LIMIT.
* text.c (vars_of_text): Make `char-code-limit' available to
Lisp.
tests/ChangeLog addition:
2015-03-15 Aidan Kehoe <kehoea@parhasard.net>
* automated/mule-tests.el (test-chars):
Use char-code-limit explicitly here, instead of hardcoding the
corresponding values.
lisp/ChangeLog addition:
2015-03-16 Aidan Kehoe <kehoea@parhasard.net>
* obsolete.el (max-char):
Make this available for compatiblity with GNU, implement it in
terms of char-code-limit.
