2.15.12 regtest problems

[Phil Holmes]

There are 2 significant problems I've found with 2.15.12.  The first is 
shown in the Les Nereides regtest - a fingering indication goes missing. 
I've attached a crop of the difference between 2.15.12 and 2.15.10 - 2.15.12 
is in red.  You'll see that the 1 on the top of the note in bar 5 has gone.

The second is performance.  On longer scores, 2.15.12 is _much_ slower.  An 
example is the mozart horn regtest, which has gone from about 14 seconds to 
27 seconds on my system.

I've not been able to check much more, because of subtle differences between 
the treble clef in 15.12 and 15.10, but that's a starter.
