Getting even more pointless here, but the portion of the line that
includes $argv:q, I think must be csh syntax (?) for ${1+"$@"}, which
implies it should work for even for csh. So, I guess I'm just saying I
don't know why it fails (unless those really are apostrophes rather
than backticks after the eval's).
