Comment #5 on issue 754 by [email protected]: \transpose should not affect
\transposition
http://code.google.com/p/lilypond/issues/detail?id=754
Fully agreed. I'd expect the respective change to be comparatively easy to
do. The problem is that it is likely to affect a _lot_ of scores. It will
also change the internals of \transposition. The special case
\transpose c' xxx { \transposition c' ...
and its companion using do' can likely be caught by convert-ly, but I guess
more complex scenarios are beyond it.
This is of the "should have been done long ago" kind. In particular, when
\transposition was affected "the wrong way around", people were likely to
avoid placing it inside of \transpose, and then one should have fixed it.
