[PATCH] searchidx: skip "delta $N" sections for base-85

[PATCH] searchidx: skip "delta $N" sections for base-85

[Eric Wong]

I don't deal with binary patches ever, so I failed to notice
binary deltas are supported in addition to the more common
literals.

A quick check of apply.c in git.git confirms "delta" and
"literal" are the only binary patch classes we can expect.
