??? The following example works fine, at least with 2.1.30:
 c4 ( \appoggiatura e8 d4 e f ) |

I guess the problem appears if you want another slur to end at the
main note after the appoggiatura/acciaccatura.

I was actually surprised myself to notice that slurs indeed can be
nested in LilyPond of neither the start nor the end point coincide.
Last time this was discussed on the list (more than a year ago), I
think the conclusion was that it doesn't make sense, musically, to
have nested slurs, except when you have a normal slur under a phrasing
slur. That's why the phrasing slurs were introduced.
Just as you, I cannot find this documented anywhere in the manual.
For a violin player like me, a normal slur means "play these notes
in the same bow", so it doesn't make sense to allow for slured grace
notes under a normal slur and the current "limitation" to only allow
for two levels of slurs (normal and phrasing) is OK. However, this
may be different on other instruments, so maybe this decision should
be reconsidered, having slured grace notes in mind.
