[PATCH v2 5/6] pathspec: remove PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP

[Brandon Williams <bmwill@google.com>]

Since (ae8d08242 pathspec: pass directory indicator to
match_pathspec_item()) the path matching logic has been able to cope
with submodules without needing to strip off a trailing slash if a path
refers to a submodule.

Since stripping the slash is no longer necessary, remove the
PATHSPEC_STRIP_SUBMODULE_SLASH_CHEAP flag.
