Perhaps something like this on top of your patch squashed in?

The eval magic lets the shell to split $strategy_opts back into
individual words (e.g. "--subtree=My Project" is a single word),
strip the leading "--", and then uses "rev-parse --sq-quote" again
to turn them into "-X 'subtree=My Project'" (two words), which can
be inserted into a string later to be eval'ed.
