From 6a289d45c0e5d155f536d7c1f73c3b33690e92c6 Mon Sep 17 00:00:00 2001 From: Matheus Tavares Date: Tue, 30 Jul 2019 13:53:27 -0300 Subject: [PATCH] grep: fix worktree case in submodules Running git-grep with --recurse-submodules results in a cached grep for the submodules even when --cached is not used. This makes all modifications in submodules' tracked files be always ignored when grepping. Solve that making git-grep respect the cached option when invoking grep_cache() inside grep_submodule(). Also, add tests to ensure that the desired behavior is performed.
