as follows:

Hi,

Now that "Measure_counter_engraver" has been implemented into LilyPond
people can add a measure counter (great, thanks).
But unfortunately people have to start it and stop it _manually_,
using \startMeasureCount and \stopMeasureCount.

Could we add a feature to have an _automatic_ measure counter for
unfold repeats?

Something like "countPercentRepeats" but for unfold repeats, that could
be named "countUnfoldRepeats".

With a "countUnfoldRepeats" property, "UnfoldRepeatCounter" object
and "Unfold_repeat_engraver".

I do not know if "repeatCountVisibility" property should be divided
into "percentRepeatCountVisibility" and "unfoldRepeatCountVisibility"
or if they could both share "repeatCountVisibility".

%%%% Example of how it would work
\relative c'' {
  \set countUnfoldRepeats = ##t
  \repeat unfold 4 { c1 }
}
%%%% End of example

Thank you in advance.

Cheers,
Xavier
