Michał Górny 72435c1a73 Interact with VCS directly when checking whole directory removal.
Use VCS functions to check whether the cached/to-be-committed version of
the working tree contains the particular directory instead of using the
local working tree. Thanks to that, the functions no longer care about
stray files.
