Currently, append_signoff() performs a search for the last line of the
commit buffer by searching back from the end until it hits a newline. If
it reaches the beginning of the buffer without finding a newline, that
means either the commit message was empty, or there was only one line in it.
In this case, append_signoff will skip the call to has_conforming_footer
since it already knows that it is necessary to append a newline before
appending the sob.
Let's perform this function inside of has_conforming_footer where it
appropriately belongs and generalize it so that we require that the
footer paragraph be an actual distinct paragraph separated by a blank
line.
