subrepo: fix test output

subrepo: print paths relative to upper repo root for push/pull/commit This makes more sense when using multiple levels of nesting. This happens to help a lot in a case where 3 projects of mine all use the same makefile helper project as a sub. A fourth project use these first three projects and current output made it very hard to figure which makefile helper was committed. it looked more like the project was committed/pushed/pulled three times in a row than dealing on three different repos.

subrepo: print pushing url

subrepo: dirtiness checks should iterate over subrepos

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
