Removed Info-lookup minor mode.
(info-lookup-file-name-alist): New variable.
(info-lookup-select-mode): New function. Select help mode
according to info-lookup-file-name-alist or fall back to the
buffer's major mode.
(info-lookup): Use info-lookup-select-mode.
(info-lookup-interactive-arguments): Likewise.
(info-complete-symbol): Likewise.
(info-complete-file): Likewise.
(info-complete): Likewise.
position for string when comparing with LIMIT.
(property_change_between_p): Likewise.
(Fnext_single_property_change, Fprevious_property_change): Likewise.
(Fprevious_single_property_change): Likewise.
default-directory if nil. Check whether default starts with a
drive specifier on windows-nt, as well as name, and call real
function if so. Remove code to strip prefix before // or /~ since
`expand-file-name' itself no longer does that.
(ange-ftp-expand-dir): Use `grep-null-device' instead of
"/dev/null", which is incorrect on windows-nt.
(ange-ftp-file-name-all-completions): Fix root directory regexp for windows-nt.
(ange-ftp-start-process): On windows-nt, always send a "help foo"
command to ensure the ftp process produces some output, and force
the process to use raw-text-dos decoding.
(ange-ftp-canonize-filename): On windows-nt, strip drive specifier
from expanded remote name.
(ange-ftp-write-region): Allow binary transfer on windows-nt if
remote host type is unix. Ensure `last-coding-system-used' is
given an appropriate value, so that basic-save-buffer isn't
confused by the coding used with the ftp process.
(ange-ftp-insert-file-contents): Ditto.
(ange-ftp-copy-file-internal): Ditto.
(ange-ftp-real-expand-file-name): Use standard definition on windows-nt.
(ange-ftp-real-expand-file-name-actual): Remove obsolete function.
(ange-ftp-disable-netrc-security-check): Make default value be t on windows-nt.
(ange-ftp-start-process): Undo previous change.
comint-next-matching-input-from-input to C-c M-r, and
comint-previous-matching-input-from-input to C-c M-s.
Move comint-get-next-from-history to C-c C-x.
(comint-accumulate, comint-goto-process-mark): Likewise.
(comint-set-process-mark, comint-bol-or-process-mark): Likewise.
(comint-save-input-ring-index): New permanent local var.
(comint-accum-marker): Likewise.
(comint-send-input): Clear comint-input-ring-index
and comint-accum-marker.
(comint-previous-matching-input-from-input):
Use comint-accum-marker if set.
(comint-previous-matching-input): Likewise.
(comint-mode): Make those vars buffer-local and initialize.
(comint-mode-map): Make C-c C-a run comint-bol-or-process-mark.
Bind C-c SPC to comint-accumulate. Bind C-c C-q to
comint-get-next-from-history.
(bookmark-jump-noselect): Use an inner save-window-excursion.
(bookmark-bmenu-switch-other-window): Temporarily set
pop-up-windows, same-window-buffer-names, and same-window-regexps,
to override Info's special display behaviors.
