Description

I have this rule in one of css files (note the extra whitespace in the url):

.b-error-page {
    background: url(../img/bg-error-page.png ) center 0 no-repeat;
}

Browsers handle this fine, collectstatic raises an exception if CachedStaticFilesStorage is used:

ValueError: The file 'img/bg-error-page.png ' could not be found with <django.contrib.staticfiles.storage.CachedStaticFilesStorage object at 0x2ee2350>.

I think css rewriter should just strip whitespaces in such cases.

Not sure if this is relevant, but anyway:
http://www.ietf.org/rfc/rfc3986 , Appendix C: "For robustness, software that accepts user-typed URI should attempt to recognize and strip both delimiters and embedded whitespace."
