tests: don't match blank output lines as regexes in unified tests

Currently, the following unified test will pass:

  $ echo foo


A blank output line (a line containing just two spaces) will match any
output.

The patch modifies the unified test runner to ignore empty strings
strings when do regular expression matching.

#!/bin/sh
# This emulates the effects of an hg pull --rebase in which the remote repo 
# already has one local mq patch
