filter-branch: handle "disappearing tree" case correctly in subdir filter
The subdirectory filter had a bug to notice that the commit in question did not have anything in the path-limited part of the tree. $commit:$path does not name an empty tree when $path does not appear in $commit. This should fix it. The additional test in t7003 is originally from Kevin Ballard but with fixups. Signed-off-by: Junio C Hamano <>
