The Underground Blog and URI hacking

[Kevin Ballard]

The Underground Blog cannot be accessed via MouseHole, because  
URI.parse() doesn't accept ___._ as a valid hostname.

Here's a patch that hacks URI to allow non-standard hosts. Applying  
this allows me to access ___._ via MouseHole.

Note: I added an entry for ___._ to ::HOSTS just for kicks. After  
looking at it, it seems that the entry for hoodwink.d isn't doing  
anything (AFAICT ::HOSTS is only used for mounts), so adding an entry  
for ___._ is useless, but I did it anyway. Or am I missing something  
about ::HOSTS?
