Faster dirty git status check (using git diff)
Closer to original status command, using SUBMODULE SYNTAX
Fixed dirty check to include files added to index
Did a full circle and went back to # On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#	modified:   git.zsh
#, ignoring untracked files, which seems to be the primary cause for slowness
