subrepo: add status support for ignored files in git subrepos
Retrieving the status of a git subrepo did not show ignored
files. Using 'git ls-files', we can retrieve these files
and display the correct status.
fixbundle() {
grep -v 'saving bundle' | grep -v 'saved backup' | \
grep -v added | grep -v adding | \
grep -v "unable to find 'e' for patching" | \
grep -v "e: No such file or directory"
}
