Crash with tupletFullLength = ##t

[Mark Knoop]

When tupletFullLength is set to ##t, the TupletBracket is actually
*shortened* by a following RehearsalMark. This doesn't happen with
tupletFullLength = ##f. 

This is merely ugly when a RehearsalMark is not so big, but if it
pushes the righthand end of the TupletBracket too far, it causes a
crash.

This would seem to be related to issue 2362
<http://sourceforge.net/p/testlilyissues/issues/2362/> however that
doesn't mention actually crashing.
