Back in edf2e37 (git-apply: work from subdirectory. - 2005-11-25),
git-apply is made to work from a subdir of a worktree. When applying a
git patch this way, only paths in the subdir are patched, the rest is
filtered out. To apply without filtering, the user has to move back to
toplevel. Add --whole to make it more convenient to do so without moving
cwd around.
