[PATCH 10/12] git rm: do not abort due to an initialised submodule

[Peter Collingbourne <peter@pcc.me.uk>]

This patch causes the "git rm" command to consider "directory not
empty" errors as nonfatal, which will be caused by a submodule being
in an initialised state.  As this is a normal state for a submodule,
it should not cause us to abort.  Neither should we recursively delete
the submodule directory as it may contain unsaved data.
