I think this is the right thing to do (at least I could not think of a
case that would be harmed by it, and it certainly fixes your case). It
looks like filter-branch would need a similar fix?

I think this still isn't resilient to weird meta-characters in the
@SHELL_PATH@, but as this is a build-time option, I think it's OK to let
people who do

  make SHELL_PATH='}"; rm -rf /'

hang themselves.
