[v3,2/2] Fix status of initialized but not cloned submodules

Commit Message

Peter Kaestle Jan. 24, 2020, 10:34 a.m. UTC

Original bash helper for "submodule status" was doing a check for
initialized but not cloned submodules and prefixed the status with
a minus sign in case no .git file or folder was found inside the
submodule directory.
This check was missed when the original port of the functionality
from bash to C was done.
