Ok.  Most of my documentation tends to be eventually replaced by
something worded more carefully.  So maybe this wants to get a do-over.

Well, the originally implemented (and documented) behavior did _not_
attach itself to chords at all, only to single notes.  The rationale was
that chords already had q for repetition and, of course, that "the
pitch" became fuzzier.  After several complaints, this behavior was
changed in the course of another issue.  It's quite possible that the
corresponding documentation changes relied too much on the original
wording.

I think it would be reasonable as a default at least for
\tabChordRepeats but I don't see a point in making \chordRepeats
different in that respect: harmonics seem like a safe bet for
repetition.
