When finalizing a commit with VC, (I usually do it from vc-next-action
but maybe there are other ways), a buffer and a window popup for
*log-edit-files*, showing the files touched by the "commit" (here
I'm using "commit" to designate the corresponding VC action
across VCSystems).

For me personally, the window is quite annoying because it's
in the path of my "C-x o" workflow: very frequently I want to jump
back to the source buffer to do some last minute adjustment.

My questions are:

1. can I get rid of the `*log-edit-files*` window & buffer?
1.2. what about just the window?
2. does the buffer serve any other purpose besides
informing me?
3. supposing the answer to 2 is "No" would some
overlay text in the *vc-log* buffer, much like the overlay
trickery that is already done there, server the same
purpose?

Would a patch that does 3 be acceptable?
