I recently discovered that although the following patch seemed to fix
the original complaint that it causes other problems (the following
tests were done in 1.3.116.
I have attached a file which has several break-volta interactions.
With the test file and unmodified 1.3.116 I see the following:
Bar 3 - 1st volta spanner centered on first note - prefer it to start
closer to key signature (can live with this)
Bar 6 - 1st volta continuation - perfect
Bar 9 - 2nd volta spanner starts on left edge of key signature - prefer
it to start right of key signature
Bar 12 1st volta starts between first two slurred notes in measure -
this is not acceptable
Bar 17 like above with hairpin.
Bar 23 like above (I had expected this to be OK)
Bar 20 2nd volta continuation perfect
With the test file and 1.3.116 modified as below I see the following:
Bar 3 Perfect
Bar 6 1st volta continuation starts with staff - oops
Bar 9 2nd volta starts on papers left margin - OOPS!
Bar 12 Perfect
Bar 17 Perfect
Bar 20 2nd volta continuation starts with staff - oops
Bar 23 Perfect
