The output of
git submodule status
will be of the following form:X
is either a space,+
, or-
git_hash
is 40 hex digitssubmodule_path
is the path in the repo where the submodule is located(git_ref)
is optional, and will not be there if the submodule is missing (which the previous regexp did not handle).This commit tightens up the regexp to be a bit more robust and handle the case where the git_ref token is not present.
