I see what you meant by the extra variables, so I've fixed that so the
original flags aren't needed with recursion. Also updated it to not
print the entering command if there is only a post-order command.
Examples:
$ git submodule foreach --recursive --post-order 'echo Goodbye' "echo \"'ello\""
Entering 'b'
'ello
Entering 'b/d'
'ello
Leaving 'b/d'
Goodbye
Leaving 'b'
Goodbye
Entering 'c'
'ello
Leaving 'c'
Goodbye
$ git submodule foreach --recursive --post-order :
Leaving 'b/d'
Leaving 'b'
Leaving 'c'
