Rename the specifier-font-matching stages in preparation for
eliminating shadowed warnings, some other related fixes from
ben-unicode-internal.
1. Rename raw enums:
initial -> STAGE_INITIAL
final -> STAGE_FINAL
impossible -> NUM_MATCHSPEC_STAGES
2. Move `enum font_specifier_matchspec_stages' from
specifier.h to lisp.h.
3. Whitespace changes to match coding standards.
4. Eliminate unused second argument STAGE in charset predicates
that don't use it -- the code that calls the charset predicates
is now smart enough to supply the right number of arguments
automatically.
5. Add some long(ish) comments and authorial notices, esp. in
objects.c.
6. In specifier.c, change Vcharset_tag_lists from a vector over
leading bytes to a hash table over charsets. This change is
unnecessary currently but doesn't hurt and will be required
when we merge in Unicode-internal.
7. In specifier.c, extract out the code that calls charset predicates
into a function call_charset_predicate().

| 27 ;; Uses the Emacs 19 terminal initialization features --- won't work with 18. | |
| 28 ;; Rewritten for Emacs 19 by jimb, January 1992 | |
| 29 ;; Cleaned up for new terminal package conventions by esr, March 1993 | |
| 30 ;; Should work well for Televideo TVI 925 although it's overkill. | |
| 31 ;; | |
| 32 ;; The Wyse50 is ergonomically wonderful, but its escape-sequence design sucks | |
| 33 ;; rocks. The left-arrow key emits a backspace (!) and the down-arrow a line | |
| 34 ;; feed (!!). Thus, you have to unbind some commonly-used Emacs keys to | |
| 35 ;; enable the arrows. | |
| 36 | |
| 37 ;;; Code: | |
