test-http: test http authentication The extension hack is based on Henrik Stuart's hg-textauth.

http: pass user to readauthforuri() (fix 4a43e23b8c55) urllib2 never handles URIs with credentials, we have to extract them and store them in the password manager before handing the stripped URI. Half of the changes deducing the username from the URI in 4a43e23b8c55 were incorrect. Instead, we retrieve the username from the password manager before passing to readauthforuri(). test-hgweb-auth.py was passing because the test itself was flawed: it was passing URIs with credentials to find_password(), which never happens.

http: strip credentials from urllib2 manager URIs (issue2885) urllib2 password manager does not strip credentials from URIs registered with add_password() and compare them with stripped URIs in find_password(). Remove credentials from URIs returned by util.url.authinfo(). It sometimes works when no port was specified as the URI host is registered too.

help: move option text display into a helper function

help: move 'additional help topics' code

help: rename option_lists to optlist

help: drop with_version If --version is specified, we print the version and exit (as documented).

dispatch: don't rewrap aliases that have the same definition Previously aliases that overrode existing commands would wrap the old alias on every call to dispatch() (twice actually), which is an obvious re-entrancy issue for things like the command server or TortoiseHG.
