subrepo: normalize path part of URLs so that pulling subrepos from webdir works For a "all projects at root" repo layout eg: /main /sub Where subrepos are used such that a clone of main has this layout: ./main/ ./main/.hgsub ./main/sub/ And the .hgsub content is: sub = ../sub This allows a pull from a hgweb where main and sub are exposed at the root (or same directory level) The current code doesn't normalize the path component of a pull url. this results in trying to pull from http://server.com/hg/main/../sub Current hgweb implementation doesn't reduce the path component so this results in a 404 error though everything is setup logically. This patch adresses this 404 error on the puller side normalizing the URLs used for pulling sub repos. For this example, the URL would be reduced to http://server.com/hg/sub Fix + test
