First, sorry for the long delay (the mail got lost)

Thanks, added the bug as percent-repeat-harakiri.ly

A workaround is to add invisible stuff to the percent repeated bars, something 
like:

<<
  \repeat percent 10 {c4 d e f }
  \new Voice {\hideNotes \repeat unfold 10 c1}
>>

Not that I know of. I'm quite sure it's possible, though, through some deep 
Scheme hacking.

I can't find a workaround either. The bug has been added as 
percent-repeat-grace.ly. Thanks!

Re: Beams across repeat signs

Of course you can work around the bug by adding a manual repeat sign, like
\repeat volta 2 { ... }\bar ":|" ...
but that's pretty silly.

Anyways, I added the bug to CVS as auto-beam-repeat.ly. Thanks!

Since multimeasure rests only make sense when they occupy full bars, lily 
automatically adds a barcheck at the start and end of each MM rest (or at 
least, it seems to be that way which looks sensible to me)

I can't reproduce - It never crashes here, neither with Pedro's 2.4.2 debian 
package nor with 2.4.3 from CVS.

Could you send the lilypond --verbose output?

Interesting.  If you delete the \paper{} and \layout{}, then
it compiles fine.  It gives warnings about rests and
notes on the same stem, but it _does_ compile.
Alternately, if you leave the \paper{} and \layout{} in there
but remove the \break s, it's still fine.
I guess the combination of raggedright and one bar per line
is too much for LilyPond to handle...?

Unless you use really strange commands, it's not much work for me to

This case is more awkward than normal, since the LilyPond example
won't compile under 2.4.2  (it doesn't like the clef.X names)
Could somebody running 2.5.x check this example?  I've just
added the final two lines, but I don't know what kind of number
I should give to middleCPosition.  If #4 isn't good, could you figure
out what number it should be?  (#0?  #10?)

Re: Two questions

I am running lilypond-book with LaTeX (Kile) on Linux with Fedora Core.
I have two questions:
1) In marking up a glyph from the Feta font, such as a prall or mordent,
is it possible to include a command that will cause the glyph to print
in a grey shade?
 

Not easily.
2) In text markups how do I include an "e with acute accent?" in a word
of French origin? I can access the character with \char #233, but when I
put it into a word there are spaces around it.
 

Just input the character directly in the file. However, make sure that 
your text editor
saves the file using Latin1 encoding (also called ISO8859-1 encoding).

Sorry, I don't understand the problem. Can you please elaborate?

(you might want to use \new Voice for the rest voices)

Re: Documentation error? How a prall is played.

[Erik Sandberg]

There may exist different conventions for this. However, J.S. Bach has written 
the following:
http://icking-music-archive.org/scores/bach/ornaments.jpg
which more or less looks like the explanations from the lilypond docs. So IMHO 
it's an OK definition.
