hgweb: remove support for short query string based aliases (BC) Form data exposed by hgweb is post-processed to expand certain shortcuts. For example, URLs with "?cs=@" is essentially expanded to "?cmd=changeset&node=@". And the URL router treats this the same as "/changeset/@". These shortcuts were initially added in 2005 in 34cb3957d875 and 964baa35faf8. They have rarely been touched in the last decade (just moving code around a bit). We have almost no test coverage of this feature. AFAICT no templates reference URLs of this form. I even looked at the initial version of paper and coal from ~2008 and they use the "/command/params" URL form and not these shortcuts. Furthermore, I couldn't even get some shortcuts to work! For example, "?sl=@" attempts to do a revision search instead of showing shortlog starting at revision @. Maybe I'm just doing it wrong? Because this is ancient, mostly untested code, there is a migration path to something better, and because anyone passionate enough to preserve URLs can install URL redirects, let's nuke the feature. .. bc:: Query string shorts in hgweb like ``?cs=@`` have been removed. Use URLs of the form ``/:cmd`` instead. Differential Revision: https://phab.mercurial-scm.org/D2773
