The proper thing to do when C-x v v is called and files are modified
depends on whether or not multiple files had been changed. If multiple
files would be committed in a single patchset, one should bring up a
dired buffer containing the modified files, allowing the user to
unmark a few. When the files have been selected, a log window should
appear. C-c C-c in this window should commit the patchset.
