Subject: 23.0.91; wacky behavior of "v" command in *vc-dir* buffer
Date: Fri, 13 Mar 2009 08:58:29 +0900

In the *vc-dir* buffer, if the cursor is on a source file entry, "v"
operates on the file under the cursor.

However, if "v" is used on a non-file line, the behavior is kind of
weird:  It pops up a *vc-log* buffer, and allows you to enter a log
message, but then typing C-c C-c (`log-edit-done') in the *vc-log*
buffer to finish the commit results in an error:

   vc-find-backend-function: Cannot open load file: vc-nil

What I _expected_ to happen is for it to commit every changed file in
the *vc-dir* buffer; this behavior is not only fairly natural (I think),
but also suggested by actions of vc prior to the error:

  (1) Using the C-c C-f command (`log-edit-show-files') *vc-log* shows
      the directory name as the "files" (in *log-edit-files* buffer)

  (2) The C-c C-c command in *vc-log*, prior to the above error,
      displays the message (where DIRNAME is the directory name):

         Checking in DIRNAME...

Thanks,

-Miles
