Is there intermediate shell run when emacs run these commands, if not,
then shell expansion isn't happen. If there is, then the "simplest" way
to avoid shell expansion is to put strings in '' -quotes and replace
all intermediate ':s with '\'' (meaning single ' expands to ''\''' ;)

These quotes are needed if emacs uses intermediate shell and emacs 
doesn't quote itself. if there is functionality change between emacs
23 and emacs 24 here, then that's interesting.
