Crescendo over repeated measures using percents

[Ben Finney]

Howdy all,

Writing a crescendo requires notation on the beginning note and the
ending note of the crescendo. But that doesn't fit well with a crescendo
across repeated measures.


The piece I'm transcribing has a section with a repeated measure. No
problem:

    \repeat percent 4 { c8.-> c16-> c8. c16 c8. c16 c8. c16 }

That presents three measures containing the repeat percent symbol, just
as I need.

The trouble is, I also needs a crescendo from the beginning to the end
of those four measures. How can I get that result?
