This will throw-away above change to "expected", I think this is not
what you expected to write!

Nit:

I suspect that we're in favour of writing all optional argument before
all committish here.

IOW, I think we're better move HEAD after --ignore-submodules=none

Another nit: I think we can avoid subshell by:
	
	echo "xxxx" >sub1/file_in_sub

In general, I think other usages of subshell in this patch could be
replaced by above syntax for echo and "git -C subdir" for git.
