(vc-default-init-version): Update documentation to
indicate that the backend can override the default init version.
(vc-register): Use the backend init-version function, if it exists, to
determine the initial version of a file.
(vc-diff-switches-list): Don't symbol-quote backend, since it's
already a symbol. Don't fail if vc-BACKEND-diff-switches isn't bound.
(vc-default-previous-version): Renamed from vc-previous-version. New
args BACKEND and FILE. Return nil for revision numbers without a `.'
(vc-version-diff): Call vc-BACKEND-previous-version.
(vc-steal-lock): Steal lock before composing mail, so that no mail is
sent when the stealing goes wrong. And we'll actually see the error
in that case now.
(vc-finish-steal): Removed.
set-buffer-modified-p to nil after `vc-exec-after'.
* log-view.el (log-view-mode-map): Bind "q", "z", "m" and "d".
(log-view-mode): Make read-only.
(log-view-current-file): Do final `expand-file-name' in the
current `default-directory'.
(log-view-current-tag): Take an optional `where' arg.
(log-view-diff): New user command.
From JD Smith <jdsmith@astro.cornell.edu>.
(vc-annotate-display-default): Accept colormap scaling
ratio (now deprecated).
(vc-annotate-display-autoscale): Added.
(vc-annotate-add-menu): New autoscaling menu options "Span to
Oldest" and "Span Oldest->Newest". Easymenu support added for
toggle menus driven by customize variable
`vc-annotate-display-mode'.
(vc-annotate-display-select): Added.
(vc-annotate): Changed temp-buffer-show-function to
`vc-annotate-display-select'.
(vc-annotate-display): Removed arguments BUFFER and BACKEND.
Added argument OFFSET. Instead of backend function, calls now
generic `vc-annotate-difference'.
(vc-annotate-difference): Added as generic function instead of
backend-specific function. No longer takes argument POINT, but
instead accepts a time OFFSET.
(vc-default-annotate-current-time): Added.
New functions.
(vc-version-diff): Use them. As a result, coding systems are now set
up properly for all sorts of diffs, and tree diffs can now also be
done locally.
(vc-diff): With a prefix argument, don't require that it's called from
a buffer under version control.
set it up and don't erase it. Updated doc string to reflect that.
(vc-version-diff): When doing a single file diff, don't switch to the
*vc-diff* buffer before the command. This is to preserve local variable
bindings that might affect the diff command.
(vc-print-log): Don't switch to the *vc* buffer before the command, so
that local variable bindings are preserved.
