* Section 7.7.7: The "episem" articulation does not appear (there should
be a horizontal line above the three last noteheads). In 2.7.x, the
right ending was badly placed; now the episem is completely invisible.
Also, the text scripts are colliding (but that is not really an ancient
notation issue); they did not collide in 2.7.x.
There are obviously multiple bugs behind this one, which are not easy to
fix. In particular, the TextSpanner under certain circumstances produces
lines with strange end points. If the line is (should be) quite short, it
is not at all displayed.
For the moment, I have tuned the figure in Sect. 7.7.7 such that the
episem is displayed (still with bad right ending) and added an appropriate
comment to the @refbugs paragraph (patch attached).
Graham, what do you think, should this patch be applied? Without this
patch, the reader of the documentation immediately sees that there must be
something wrong but is left alone, as the figure does not show what is
explained in the text. With the attached patch, the reader will
(hopefully) see that episem to some extent works (to the same extent as in
the lily 2.7.x series), but there is an explanation in the @refbugs
paragraph that states that the episem feature is rather buggy.
Of course, I would like to get this bug fixed, but it looks like I would
have to rewrite major parts of TextSpanner and LineSpanner.
Greetings,
Juergen
