Not all valid attribute selectors are recognized

[akhleung]

Attribute selectors of the form [attr] aren't recognized; the parser currently expects to see the attribute matched against a string value (e.g., [attr="blah"]).

Fixed.

This does not seem to be fixed.

Certain kinds of attribute selector matching—e.g. span[class|="lang"]—still throw an error, although they should be valid.

this also throws an error

*[class|="has-background"] {
    background: #efefef;
    padding: 7px;
    border: 1px solid #888;
    margin-bottom: 5px;
    }

spits out

error: invalid attribute name in attribute selector

it seems that http://css2sass.heroku.com/ can correctly parse it, so i'm suspecting its libsass at work here.

Hmm, seems to be the |= operator that LIbSass doesn't like; thanks for the report. Also, whenever you find a valid bug in a closed ticket, please re-open the ticket -- otherwise it might fall through the cracks!

@hcatlin Unfortunately in that case, only people with commit access or the person who opened the issue can re-open it.

Okay, I pushed a fix to master. Please give it a try!
