merge: --log appends shortlog to message if specified

When the user specifies a message, use fmt_merge_msg_shortlog() to
append the shortlog.

Previously, when a message was specified, we ignored the merge title
("Merge <foo> into <bar>") and shortlog from fmt_merge_msg().

Update the documentation for -m to reflect this too.
