* octave-mod.el (octave-font-lock-keywords): To font-lock the
builtin operators, use `font-lock-builtin-face' for Emacs and
`font-lock-preprocessor-face' otherwise.
* font-lock.el (lisp-font-lock-keywords-1): Highlight
`(defun (setf foo)' differently.
2000-03-08 Stefan Monnier <monnier@cs.yale.edu>
* emacs-lisp/regexp-opt.el: Update copyright and leading comment.
(regexp-opt): Update comment and adapt the code the new meaning of the
`paren' argument of regex-opt-group for shy-groups.
(regexp-opt-depth): Handle shy groups as well as backslashed backslashes.
(regexp-opt): Update comment and adapt the code the new meaning of
the `paren' argument of regex-opt-group for shy-groups.
(regexp-opt-depth): Handle shy groups as well as backslashed
backslashes.
(regexp-opt-group): Turn the leading comment into a docstring.
Allow `paren' to be a string (the string to use to open a group).
Remove open-presuf and close-presuf.
Instead of checking for `all one-char' and then later on check for
`several one-char', handle both cases close together.
Also apply a more generic algorithm for suffixes (the mirror image
of the algorithm used for prefixes).
Use shy-groups. Use nreverse rather than reverse.

(regexp-opt-try-suffix): Removed.
* cmuscheme.el (inferior-scheme-mode-map): Define it independently
from comint-mode-map, so we can just inherit from it. Also, move the
initialization into the `defvar' since there's no docstring anyway
and it's fairly short.
(inferior-scheme-mode): Define it as derived-mode: the code is shorter
and this way we inherit from comint-mode-map rather than copying it.

* subr.el (replace-regexps-in-string): Properly handle the case where
we match an empty string.

* comint.el (comint-exec-1): Add the current-dir to the exec-path when
the command has a directory component (such as "./testml").

Also fix a typo in the comment.

(RE_UNMATCHED_RIGHT_PAREN_ORD): Renumber.
(RE_SYNTAX_EMACS): Add RE_SHY_GROUPS.
* regex.c (enum re_opcode_t): Remove jump_past_alt, maybe_pop_jump,
push_dummy_failure and dumy_failure_jump.
Add on_failure_jump_(exclusive, loop and smart).
Also fix the comment for (start|stop)_memory since they now only take
one argument (the second has becomes unnecessary).
(print_partial_compiled_pattern): Adjust for changes in re_opcode_t.
(print_compiled_pattern): Use %ld to printf long ints and flush to make
debugging a little easier.

The pattern address pushed is not the destination of the jump

(regex_compile): Add shy-groups
Change loops to use on_failure_jump_smart&jump instead of
on_failure_jump&maybe_pop_jump.
Change + loops to eliminate the initial (dummy_failure_)jump.
Remove c1_base (looks like unused variable to me).
Use `jump' instead of `jump_past_alt' and don't bother with
push_dummy_failure in alternatives since it is now unnecessary.
Use FIXUP_ALT_JUMP.
Eliminate a useless `#ifdef emacs' for (re)allocating the stack.
(re_compile_fastmap): Remove dead variables i and num_regs.
Exit from loop when bufp->can_be_null rather than jumping to `done'.
Avoid jumping backwards so as to ensure termination.
Use PATTERN_STACK_EMPTY and POP_PATTERN_OP.
Improved handling of backreferences.
Remove dead code in handling of `anychar'.

(skip_noops, mutually_exclusive_p): New functions taken from the

Slightly improve mutually_exclusive_p to handle ".+\n".
((lowest|highest)_active_reg, NO_(LOWEST|HIGHEST)_ACTIVE_REG)
Remove.
(re_match_2_internal): Use %p instead of 0x%x when printf'ing ptrs.
Don't SET_REGS_MATCHED anymore. Remove many dead variables.
Push register (in `start_memory') on the stack rather than storing it
in old_reg(start|end).
Remove the cycle detection from `stop_memory', replaced by the use
of on_failure_jump_loop for greedy loops.
Add code for the new on_failure_jump_<foo>.
Remove ad-hoc code in `on_failure_jump' to push more registers
in the case of a loop.
Take out code from `maybe_pop_jump' into separate functions and
adapt it to the semantics of `on_failure_jump_smart'.
Remove jump_past_alt, dummy_failure_jump and push_dummy_failure.
Remove dummy_failure handling and handling of `failures to jump
to on_failure_jump' (this last one was already dead code, it seems).
