emacs loads version control packages in batch mode

[jalitr]

Binary package hint: emacs23

If you are in a source repository, emacs loads the version control
package for that repository in batch mode. The problem can be
reproduced as follows:

    # Create an empty directory.
    $ mkdir tmp
    $ cd tmp

    # Verify there is no problem in the empty directory.
    # These commands should not produce any output.
    $ emacs -Q --batch --load /dev/null
    $ emacs -Q --batch --load /dev/null foo

    # Pretend to put the directory under version control.
    $ mkdir .git .hg .svn CVS
    $ touch CVS/Entries .svn/entries

    # Verify that the first command is still ok.
    $ emacs -Q --batch --load /dev/null

    # Verify that the second command prints the loading messages
    # which are inappropriate for batch mode.
    $ emacs -Q --batch --load /dev/null foo
