find-file-of-tag to avoid name space pollution.
(tag-find-file-of-tag-noselect): Likewise.
(etags-list-tags, etags-tags-apropos): Use
tag-find-file-of-tag instead of find-file-of-tag.
(snarf-tag-function): Doc string is changed. Explained about new optional
argument, `use-explicit'.
(etags-snarf-tag): Added one optional argument `use-explicit'.
(file-of-tag-function): Doc string is changed. Explained about new optional
argument, `relative'.
(file-of-tag): Doc string is changed. Explained about new optional argument,
`relative'. Pass `relative' to `file-of-tag-function'.
(etags-file-of-tag): Added new argument `relative`.
(list-tags): Set `buffer-read-only' to t after making the major mode
apropos-mode.
(etags-list-tags): Used `make-text-button' instead of `add-text-properties'.
Used `snarf-tag-function', `goto-tag-location-function' and `find-file-of-tag'
instead of `find-tag-other-window' (it's too simple).
(find-tag-in-order): Used `find-file-of-tag-noselect' instead of `find-file'.
(etags-tags-apropos): Used `find-file-of-tag-noselect' instead of `find-file'.
Do not use `etags-goto-tag-location` directly; use `goto-tag-location-function'
instead. Print relative file paths instead of complete ones in *Tags List*
buffer, so lines in the buffer become shorter.
(etags-tags-apropos-additional): Use `make-text-button' instead of
`add-text-properties'.
(etags-tags-apropos): Use make-text-button instead of add-text-properties. Use
snarf-tag-function and etags-goto-tag-location instead of find-tag-other-window
(it's too simple).
(asm-mode): Use them in indent-line-function.
Set tab-always-indent to nil to stay closer to previous tab behavior.
Set comment-add. Remove space at end of comment-add.
(asm-newline): Obsolete. Use newline-and-indent instead.
(asm-mode-map): Remove TAB binding.
(asm-code-level-empty-comment-pattern)
(asm-flush-left-empty-comment-pattern)
(asm-inline-empty-comment-pattern): Remove.
(asm-comment): Use newcomment functions instead.
(asm-colon): Don't tab if colon is not after a label.
(asm-line-matches, asm-pop-comment-level): Remove.
(asm-mode-map): Declare and init at the same time.
(asm-code-level-empty-comment-pattern)
(asm-flush-left-empty-comment-pattern)
(asm-inline-empty-comment-pattern): Use \s< so they do not depend
on asm-comment-char. Turn them into constants.
(asm-mode): Simplify.
(asm-line-matches): Remove unused arg.
(toplevel): Require man.
(condition-case): Don't autoload tmm-prompt (it's in loaddefs.el).
(cperl-electric-backspace-untabify): New var.
(cperl-electric-backspace): Use it.
(cperl-vc-header-alist): Extract numeric version from the Id.
(cperl-build-manpage): New fun.
(cperl-menu): Use it. Add toggle-autohelp.
(cperl-mode) <defun-prompt_regexp>: Understand prototypes.
(cperl-electric-brace): Use `cperl-after-block-p' for detection.
(cperl-electric-keyword): Make $if (etc: "$@%&*") non-electric.
'(' after keyword would insert a doubled paren.
(cperl-calculate-indent): Update syntaxification before checks.
Fix wrong indent of blocks starting with POD.
(cperl-find-pods-heres): If no end of HERE-doc found, mark to the end
of buffer. This enables recognition of end of HERE-doc "as one types".
Require "\n" after trailing tag of HERE-doc.
\( made non-quoting outside of string/comment (gdj-contributed).
Likewise for \$. Remove `here-doc-group' text property at start
(makes this property reliable).
Text property `first-format-line' ==> t.
Do not recognize $opt_s and $opt::s as s///.
(cperl-after-block-p): Optional arg pre-block to check for a pre-block
Recognize `continue' blocks too.
(cperl-after-expr-p): Update syntaxification before checks. Work after
here-docs, formats, and PODs too (affects many electric constructs).
(cperl-fix-line-spacing): Allow "_" in $vars of foreach etc.
(cperl-perldoc): Use case-sensitive search.
(cperl-xemacs-p): Move.
(cperl-can-font-lock): New var to replace window-system.
(cperl-enable-font-lock): Use it.
(cperl-use-major-mode): New var.
(cperl-mode): Use it.
(cperl-calculate-indent): Remove code whose removal was missed
in some earlier merge.
(cperl-tags-hier-init): Use display-popup-menus-p.
(ebnf-syntactic): Change group name and tag from "ebnf-syntatic".
(ebnf-syntax, ebnf-lex-comment-char, ebnf-lex-eop-char, ebnf-terminal-regexp)
(ebnf-case-fold-search, ebnf-iso-alternative-p, ebnf-iso-normalize-p)
(ebnf-yac-ignore-error-recovery): Add to group "ebnf-syntactic", not
"ebnf-syntatic".
(ebnf-optimize, ebnf-print-buffer, ebnf-print-region, ebnf-spool-buffer)
(ebnf-spool-region, ebnf-eps-buffer, ebnf-eps-region, ebnf-syntax-buffer)
(ebnf-syntax-region, ebnf-generate-region): Fix typo.
