bug#12153: 24.1.50; vc-checkin fails when buffers of files doesn't exist.

[Thierry Volpiatto]

Hi,
trying to use `vc-checkin' from lisp, I found that it is not usable when
the buffers of the files I want to commit are not present.
This is due I think to the concept of `with-vc-properties' that need
some buffer properties to get info on files (there is a note about this in
the definition of `vc-checkin').
I understand that when commiting changes vc can expect the buffer of the
modified file is present, but when adding new files, this may not be
true.

Also when an eshell buffer is present, vc ask about this buffer, which
is wrong (but that's maybe another bug).
