Prevent false mod_rewrite error

If Google's Closure Compiler API is enabled, rewriteTest.js is served as
"1;" instead of "1". Therefore the "Note: Your webserver does not seem
to support mod_rewrite (used in /min/.htaccess). Your Minify URIs will
contain '?', which may reduce the benefit of proxy cache servers." is
wrong. This is a simple workaround.
