Re: [PATCH] Do not ignore merge options in interactive rebase

You should use ${var:+if_set_to_nonempty_use_this} here.

So munging it manually with sloppy "sed" script is simply wrong.

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.
