before starting the expensive rcs2log process.
Use call-process instead of shell-command to invoke rcs2log;
this avoids undesired shell escapes and is more robust about errors.
Put mark at point-min, so that the new insertion is in the region.
(vc-checkin-hook): Fix `runs-hooks' typo.

was applied to a new file while vc-initial-comment was non-nil.
(vc-register): Don't barf when registering a new, empty buffer.
(vc-directory): The `No files are currently registered'

...), since the 'funcall is redundant.
When traversing a directory tree, message
"Traversing directory XXX" so that the user can see what progress is
being made. Traversal can take a long time. Omit first argument,
since it is always the current directory. All callers changed.
