It is not surprising that this didn't work, because that was a
different implementation of makeinfo, which had various differences in
how macros were interpreted.

Clearly, the comma in the @value is being taken as ending the argument
to @uref. I don't know if the way it is being done at the moment is
correct: it depends on when exactly the @value is expanded, before or
after the argument is extracted.

There is the @comma command that looks like a good solution in this
situation, and which avoids any possible ambiguity.

@uref{http://imslp.org/wiki/Repository_of_Music-Notation_Mistakes_%28Coulon@
>comma{}_Jean-Pierre%29, this book}

produces the correct output for me.
