I see you made this internal to the caching code, but I suspect in the
long run there needs to be a way for callers that use the caching
mechanism to check and then create new paths in the work tree to
invalidate the cached code (namely, builtin-apply.c::write_out_results()
and entry.c::checkout_entry() codepaths).

I'll queue this round to 'pu' anyway, though.

Thanks.
