Taking a look at the collision handling I freaked out.  The way I read
the code, extra objects avoid at most exactly _one_ slur (including
phrasing slurs) which tends to be the first in the group of the last
encountered kind, basically the one entered into its grob object "slur"
at the time it is being typeset.

This is disturbing, yes.
