refresh patch

This change is required after de-parameterizing the i2prouter script.  I
hardcoded the file name because the $0 variable isn't expanded (because of
single quotes). When using double-quotes (and escaping with back-slashes), the
strings weren't translated. I've decided to de-parameterize until I figure out
what the problem is.
