I conject that (1) will be fixed also if bendAfter is taken into account 
by horizontal spacing. So I created a single issue, 4711 
<https://sourceforge.net/p/testlilyissues/issues/4711/>. In case the fix 
for (2) should not fix (1), we can easily open a separate issue for (1).

I agree, that’s ugly. (Both examples, actually, but the first is due to 
4711)
