variable now defaults to Emacs's absolute file name, instead of
to "t".
* etc/PROBLEMS: Adjust tcsh advice for this.
* make-dist (EMACS): Exit and fail if the EMACS environment
variable is set to something other than an absolute file name.
* lisp/comint.el (comint-exec-1): Set EMACS to the full name of Emacs,
not to "t".
* lisp/progmodes/compile.el (compilation-start): Likewise.
* lisp/progmodes/idlwave.el (idlwave-rescan-asynchronously):
Don't use expand-file-name on invocation-directory, since this
might mishandle special characters in invocation-directory.
* man/faq.texi (Escape sequences in shell output): EMACS is now set
to Emacs's absolute file name, not to "t".
(^M in the shell buffer): Likewise.
* man/misc.texi (Interactive Shell): Likewise.
(idlwave-is-continuation-line): Always return point at start of previous
non-blank continuation line.
`keyword-parameters': Fix continued comment font-lock matcher.
(idlwave-font-lock-fontify-region): Written, use as
font-lock-fontify-region-function, to fix continued keyword
fontification issues.
* textmodes/flyspell.el (flyspell-large-region):.
* progmodes/make-mode.el (makefile-query-by-make-minus-q):
* emulation/viper-util.el (viper-glob-unix-files):
* emacs-lisp/shadow.el (shadow-same-file-or-nonexistent):
* man.el (Man-init-defvars):
* jka-compr.el (jka-compr-call-process):
* files.el (get-free-disk-space,insert-directory):
* ediff-ptch.el (ediff-test-patch-utility):
* ediff-diff.el (ediff-test-utility):
* dired-aux.el (dired-check-process):
* mail/sendmail.el (sendmail-send-it): Don't use = or zerop to
test the return value of call-process, because it can be a string.
Add a \ in front of open-paren-in-column-0 in docstrings. Otherwise
indentation and font-lock get confused.
(idlwave-function-menu): Use defalias so the funs are called interactively.
Don't rely on knowledge about which Emacs provides imenu or func-menu.
(idlwave-calculate-cont-indent): Fix typo.
(idlwave-font-lock-keywords-*): Don't use setq on a defconst.
Remove unused variables.
(idlwave-rw-case, idlwave-elif, idlwave-case, idlwave-for,
idlwave-if, idlwave-procedure, idlwave-function, idlwave-repeat,
idlwave-while): respect `idlwave-reserved-word-upcase'.
(idlwave-rw-case): New function.
(idlwave-statement-match): Fixed problem with assignment regexp.
(idlwave-font-lock-keywords): Improved regexp for keyword
parameters.
(idlwave-surround): New argument LENGTH to support padding of
operators longer than 1 char.
