[PATCH v2 1/3] gitweb: Cleanup git_print_log()

[Namhyung Kim <namhyung@xxxxxxxxxx>]

If $signoff set to 1, the $line would be handled in
the if statement for the both cases. So the outer of
the conditional always sees the $signoff always set
to 0 and no need to check it. Thus we can finally get
rid of it.

Also rename $empty to more clear $skip_blank_line as
suggested by Junio.
