test coverage

[Han-Wen Nienhuys]

Hi,

I've been running coverage tests of the input/regression/ suite, to
see which parts of the code are not excercised.  This has already
turned up some bugs.

You can get a full overview by running buildscripts/build-coverage.sh,
but here are some interesting offenders


cov % ( lines): file

 5.04 (   238): vaticana-ligature-engraver.cc
52.49 (   341): lookup.cc
 0.00 (   132): page-turn-page-breaking.cc
 3.10 (   129): vaticana-ligature.cc
 7.27 (   110): gregorian-ligature-engraver.cc
61.33 (   225): page-spacing.cc
64.14 (   145): page-turn-engraver.cc



Joe - can you look into writing a couple of tests for the
page-breaking stuff?
