[PATCH] More bugfixes

[Juergen Reuter]

Though I have attached some more bugfixes, just for the record (also for
myself to remind), here are some more open issues:

* output-lib.scm, function find-notehead-symbol:
  often switches between note heads of different font-families
  (e.g. baroque: optionally select (neo_)mensural note heads), which
  will not work (unless font-family is automatically changed).
  Possible solution 1: move neo_mensural stuff from parmesan to feta
  Possible solution 2: in find-notehead-symbol, also include font-family

* time signature is still broken, since style-alist in font.scm (or
  rather the lookup function that operates on style-alist) assumes a
  single, unique font family (which is currently "music").

* segmentation fault (in 1.5.33; I actually didn't check this in 1.5.34):

* N.B.: To get this (still too short or maybe even corrupted?)
  backtrace, I had to run lilypond from the lily/out directory, since
  debugging symbols were stripped off when doing "make install",
  although --enable-debugging had been set.  Is this intended
  behaviour?

* Similarly, when doing a "make distclean" I would expect to get the
  same status lilypond is put on the web.  However, "make distclean"
  removes make/out/lilypond.* and
  Documentation/pictures/out/lilypond-icon.xpm.  Since these files are
  distributed with the lilypond sources, I would expect these files to
  stay on distclean.  Currently, I always have to manually adjust
  these differences when creating a patch.

Greetings,
Juergen
