(vc-next-action-dired): Use dired-do-redisplay. Handle

window configuration correctly.
(vc-next-action): Save window configuration for vc-next-action-dired.
(vc-finish-logentry): Only kill log buffer if it does exist.
(vc-dired-mode): Rewritten so that it works entirely through
dired-after-readin-hook.  Subdirectories are handled just as in
ordinary dired.
(vc-dired-hook): New function.
(vc-state-info, vc-dired-reformat-line): Adapted.
(vc-dired-update, vc-dired-update-line): Removed.
(vc-directory): Rewritten.
(vc-directory-18): Removed.
(vc-dired-mark-locked): New function, bound to "*l" in vc-dired-mode.
(vc-do-command): Only compute vc-name if it is really needed.
(vc-fetch-cvs-status): New function.
(vc-dired-hook): Use it.

"The major mode used in VC directory buffers. It works like Dired,
but lists only files under version control, with the current VC state of
each file being indicated in the place of the file's link count, owner,
group and size. Subdirectories are also listed, and you may insert them
into the buffer as desired, like in Dired.
All Dired commands operate normally, with the exception of `v', which
is redefined as the version control prefix, so that you can type
`vl', `v=' etc. to invoke `vc-print-log', `vc-diff', and the like on
the file named in the current Dired buffer line. `vv' invokes
`vc-next-action' on this file, or on all files currently marked.
