From c08397e3aa46fd0f0da29dfe5b257839b9c5d1c8 Mon Sep 17 00:00:00 2001 From: Brandon Williams Date: Thu, 11 May 2017 15:04:24 -0700 Subject: [PATCH] pathspec: remove PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag 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 the stripping the trailing slash is no longer necessary, remove the PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag. In addition, factor out the logic which dies if a path decends into a submodule so that it can still be used as a check after a pathspec struct has been initialized.
