Major change in v5 is to use tree_is_interesting api instead of the vanilla
pathspec code for submodules. This is to fix the issue in the last seires
where I mix the two types. More tests were also added to ensure that the
changes to the pathspec code functioned properly.
Brandon Williams (6):
submodules: add helper functions to determine presence of submodules
submodules: load gitmodules file from commit sha1
grep: add submodules as a grep source type
grep: optionally recurse into submodules
grep: enable recurse-submodules to work on <tree> objects
grep: search history of moved submodules
