(makefile-rule-action-regex): Turn it into a var, and refine it so it recognizes backslashed continuation lines as belonging to the same command.
(makefile-macroassign-regex): Refine it so it recognizes backslashed continuation lines as belonging to the same command.
(makefile-var-use-regex): Don't look at the next char, because it might be the same one to be skipped by the initial [^$], leading to an overlooked variable use.
(makefile-make-font-lock-keywords): Remove two parameters, which are now variables that some of the modes set locally. Handle dependency and rule action matching through functions, because regexps alone match too often. Dependency matching now comes last, so it can check, whether a colon already matched something else.
(makefile-mode): Inform that font-lock improves makefile parsing capabilities.
(makefile-match-dependency, makefile-match-action): New functions.
tooltip-change-major-mode.
(gud-tooltip-print-command): Remove case where gud-minor-mode
is gdb ("--fullname").
(gud-tooltip-tips): Turn GUD tooltips off for this case and
explain to user.
overlay-arrow-string to "" always.
(compilation-set-window): Left fringe then don't scroll. No left
fringe then no arrow and scroll message to top.
(compilation-context-lines): Adjust doc string accordingly.
(ido-magic-delete-char): New commands for C-f, C-b, C-d.
(ido-wide-find-dir-or-delete-dir): New command for M-d.
(ido-define-mode-map): Bind them. Add C-x prefix to fallback commands.
(ido-read-file-name): Handle commands with ido property value
equal to find-file as reading a file name, to allow C-d to enter dired.
(ibuffer-find-file): Add ido property with value find-file.
Use calc-var-name for variable name.
(calc-store-into): Add the result of calc-store-value to message.
(calc-copy-variable): Add a message.
(calc-store-exchange): Improve error messages.
(calc-store-binary, calc-store-map): Don't reset the values of special constants.
Make the function handle non file visiting buffers correctly.
(hack-local-variables-prop-line, hack-local-variables)
(hack-one-local-variable): Use STRING arg of `hack-local-variables-confirm'.
(sc-recite-frame-alist, sc-default-cite-frame)
(sc-default-uncite-frame, sc-default-recite-frame)
(sc-attrib-selection-list, sc-rewrite-header-list):
