The above looked very odd to me, having that dollar sign in the middle of 
the regular expression. It wasn't until I was deep into the fetcher's code 
that I realized that it is not actually one regular expression above, but 
three, formatted as a URL...

However, based on the code in bitbake/lib/bb/fetch2/__init__.py:uri_replace(), 
AFAICT, the dollar sign should not be needed above, as it will be added for 
the URI type regexp automatically. The same goes for the other two URLs in 
mirrors.bbclass that use that formatting.

While investigating this, I also tried to look in the bitbake documentation 
for a description of the format used for the PREMIRRORS and MIRRORS variables, 
but I could not find any. There is only a simple example, without any 
explanation for the actual format that is being used.
