[PATCH 2/2] Fix t3404 assumption that `wc -l` does not use whitespace.

t3404-rebase-interactive used `grep -Fx 0` to match against `wc -l`
output.  This fails on OS X and any other system where wc outputs
whitespace.  Use `test 0 = `... instead, like we do in other tests.

 Should this construct go into CodingStyle?  I seem to have to write
 patches like this every month or so.
