Comment #15 on issue 2584 by [email protected]: please make partcombine
merge slurs
http://code.google.com/p/lilypond/issues/detail?id=2584
Re: comment 14 first paragraph, \partcombine does not want to generate
concurrent slurs.
When inner chair violins play {e'2( f'4 g') g'2( f')}
and outer chair violins play {c'2( f'4 g') e'2( d')}
a score often shows both divisi parts on a single staff, and when the
rhythms match, as a single voice. Formerly Lilypond analyzed the combined
part as : a slur starting on e' and the same slur starting on c', and later
that same slur ending on g'.
Commit b986b38f14 causes wrong output for this common case, and makes the
relevant regressions test disagree with its self-description. That commit
avoided a warning from partcombine, in response to issue 1967, but the
resulting incorrect output is worse than a warning, so we need to revert
b986b38f14
The patch of comment 1 addresses issue 1967 by implementing rules:
warn when we see ( but "already have a slur" that started earlier
warn when we see ) but there is no slur to end
treat multiple simultaneous (s or )s as redundant requests.
If there is good reason to reject the patch of comment 1, we can simply
revert b986b38f14
