  13 I recently discovered that although the following patch seemed to fix
  14 the original complaint that it causes other problems (the following
  15 tests were done in 1.3.116.
  16
  17 I have attached a file which has several break-volta interactions.
  18
  19 With the test file and unmodified 1.3.116 I see the following:
  20
  21 Bar 3 - 1st volta spanner centered on first note - prefer it to start
  22 closer to key signature (can live with this)
  23 Bar 6 - 1st volta continuation - perfect
  24 Bar 9 - 2nd volta spanner starts on left edge of key signature - prefer
  25 it to start right of key signature
  26 Bar 12  1st volta starts between first two slurred notes in measure -
  27 this is not acceptable
  28 Bar 17  like above with hairpin.
  29 Bar 23  like above (I had expected this to be OK)
  30 Bar 20  2nd volta continuation perfect
  31
  32 With the test file and 1.3.116 modified as below I see the following:
  33
  34 Bar 3   Perfect
  35 Bar 6   1st volta continuation starts with staff - oops
  36 Bar 9   2nd volta starts on papers left margin - OOPS!
  37 Bar 12  Perfect
  38 Bar 17  Perfect
  39 Bar 20  2nd volta continuation starts with staff - oops
  40 Bar 23  Perfect
