Re: [PATCH] Teach filter-branch about subdirectory filtering

Good thing you folded git-split into this, which is an obviously right thing to do.

But it makes me wonder, if it is common to want to split a combined project into two (or more) sets, taking more than one directories at a time. Contents of directory A and B (without hoisting them up) are filtered into one history and remaining bits (again without hoisting them up) are filtered into another.

I do not think that is common, and you can easily do that with the index filter, I think, so it probably is pointless to make this new filter to try supporting that mode of operation.

We might however want to make sure that we detect an attempt to give more than one --subdirectory-filter parameter.
