Patch for Links to support about:blank

[Tom]

I wrote a patch for Links to support about:XXX URLs by returning an 
empty result.  I find the reasoning that "we don't care that Mozilla 
supports a nonstandard feature but for Links we're going to be all 
uptight" to be, well, bothersome.  I like orthogonality.

Until Mozilla removes support for it, I'll keep patching Links, even if 
only I care :-)
