I found in the Tips and Tricks for the current stable version:
http://lilypond.org/doc/v2.10/input/test/lily-cd92ad8b64.ly

Then I:
* Added three to the compound-time define block (list?);
* Removed "#:lower 1" (which I correctly interpreted to mean "move this
markup down one staff space") because I wanted the + signs to be in the
numerator; and
* Took a chance that LilyPond wouldn't cough or die when it encountered the
missing "num" in the "denominators" (yes, I know they aren't true fractions,
but whatever) of the first and third time signatures.

Not only did Lily neither cough nor die, she didn't even blink -- 0 errors,
0 warnings.

Had I known it existed, I probably wouldn't have looked elsewhere for
inspiration ... though I probably would have ground my teeth for all those
eights in the "denominators"

You're too kind -- but the credit belongs with the creator of the Tip that I
mangled ... err ... adapted to my purpose.

Most likely, yes.

Thank you, that worked like a charm!

'Mmm-kay!
