For this, VC-log needs to count how many revisions it is showing and
compare with the number of revisions on the branch. Looks like too much
work. OTOH, on some backends (i.e. git) it is difficult to differentiate
the first (oldest) revision from any other on the log listing, as it
lacks revision numbers.

It seems that git does not append a newline to the last revision. The
buttons look fine for Subversion and Bazaar, although a blank line
before them would be aesthetically pleasant.
