Re: Formatting bug with 2.10.20

First of all, I don't think it's a bug. It's rather an example of an ill chosen 
line break (or rather an unfortunate choice of LilyPond not to include a
line break). It seems that the line breaking mechanism in LilyPond thinks that the full piece is short enough that everything can fit on a single line. When you add the transposition, more accidentals are inserted which take horizontal space, so LilyPond can no longer fit it into a single line, but breaks it into two lines, 
which of course gives a much looser spacing. In my experience, this has only
happened for short pieces. As soon as your score has at least 2 systems, then it will insert line breaks long before the spacing is this tight. The simple workaround 
is to manually insert a \break at an appropriate place.
Secondly, the "bug" seems to be fixed in version 2.11.20, i.e. you get the same 
line breaking with both versions of your example.

I've found a weird formatting bug.

In the attached file, the exo117a.ly is wrongly formatted on a single
line, as you can witness in the attached PNG rendering.

Changing the line 57 to read:

        \transpose d fis { \CanonLeaderThird \CanonBodyThird }

will produce something musically incoherent, but which formats
correctly, as witnesses by the attached exo117a-fix.png.

This is very annoying because even if I add a manual \break in the
correct version, the very last note is typesetted too close to the
ending bar.  So there's something abnormal going on here.
