mktag doc: grammar fix, when exists -> when it exists

Amend the wording of documentation added in 6cfec03680 (mktag:
minimally update the description., 2007-06-10). It makes more sense to
say "when it exists" here, as we're referring to "the message".

@ -29,7 +29,7 @@ has a very simple fixed format: four lines of
tagger <tagger>
followed by some 'optional' free-form message (some tags created
by older Git may not have `tagger` line). The message, when
by older Git may not have `tagger` line). The message, when it
exists, is separated by a blank line from the header. The
message part may contain a signature that Git itself doesn't
care about, but that can be verified with gpg.
