And why is it a bad thing?  If you meant s/--interactive/-m/ in the
above, then I can sort of understand the justification, though.

I see an unjustifiable mode change here.

So you _did_ mean "rebase -m"?

This is a bad change.

I would understand if the above were:

	git cherry-pick ${strategy+--strategy=$strategy} ...

in other words, "if there is no strategy specified, do not override
the configured default that might be different from recursive"
(pull.twohead may be set to resolve).

Is it guaranteed $startegy_opts do not have a space in it?

There is a call to "git merge" that uses "${strategy+-s $strategy}",
but it does not seem to propagate the strategy option.  Does it need
a similar change?  It seems that the first step might be to factor
out these calls to the "git cherry-pick" and "git merge" to helper
functions to make it easier to call them with -s/-X options in a
consistent way.

It seems that there is another call to "git cherry-pick" in the
script ("git grep" for it).  Does it need a similar change?
