cssurlrewrite.php has faulty regex

[katarak]

line 31 of cssurlrewrite.php has the following line:
fwrite($output, preg_replace_callback('/url(\s_'"['"]?\s_)/i', 'replace_css_url', $css));
unless I'm mistaken the line should be like this:
fwrite($output, preg_replace_callback('/url(\s_['"]?(.?)['"]?\s)/i', 'replace_css_url', $css));
I've added a '?' here: '/url(\s*['"]?

if not anything in the css that is:
url(path/to/img/img.ext)
will not work.

at least it didn't in my tests... the preg would not find them.

not sure what your 'i' does at the end of expression either. removing it didn't change any of my code.

Yeah, it looks like it has a bug that misses the case when CSS doesn't have quotes around the URL (specifically, it requires first quote).

//i does case insensitive search so if you had URL('...') instead of url('...')

Hope it fixed it in afc91d2

Please try again.
