Thomas's oldest one looked like a good starting point but we've
gained a codepath to spit out the contents of notes since then, which
probably needs to be killed at least for this codepath.

A few problems I noticed while looking at log-tree.c and pretty.c

 * pretty_print_commit() shows notes at the end of existing
   message.  There is no provision for the callers to affect what
   comes between the existing log message and the notes text.

 * show_log() has the "add-signoff" that appends a sign-off after
   whatever pretty_print_commit() gives.

Taken together, they make it unnecessarily cumbersome to inject a
new sign-off and "---" between the log message and notes.

The easiest is to add another parameter to pretty_print_commit that
is inserted immediately after the log message before notes are
appended.  That way, we can update show_log() to first format
additional sign off (if needed) and then "---\n" (again, if needed)
to a new strbuf and pass it as the new argument when calling the
pretty_print_commit() function.
