test-subrepo: glob away an unstable hash
This is the instability mentioned at the beginning of the series. I don't like
hiding it, but I don't want to sit on a fix for a user reported problem while
trying to figure this out.
The instability seems related to the cset with a .hgsub with a remote URL.
(There's very little existing remote URL subrepo testing.)

This module implements GET, HEAD, POST, PUT and DELETE methods
on BaseHTTPServer, and behaves as an HTTP proxy. The CONNECT
method is also implemented experimentally, but has not been
tested yet.
Any help will be greatly appreciated. SUZUKI Hisao
