I wonder if it's overkill to do something like this patch ("git
archive" may need some more updates for it to work though). With it
you can do:
git diff --name-only ... | git archive ... HEAD -- ":(file)-"
The good thing is it works for other commands as well. But is it
really a good thing..

Subject: [PATCH] pathspec: support :(file)
This pathspec magic must be used alone. It reads the actual pathspec
from a given file whose path is specified after :(file). E.g.
git ls-files :(file)foo
list files specified by pathspec in file "foo". Reading from stdin is
possible to:
git ls-fiels :(file)-
TODO: specify line terminator..
