These URLs kill me, I share a lot of links and these branches use full commit strings (instead of just "default" or "stable" human readable) and the links it creates to PRs includes the actual title (which I find I can delete manually, but this is the default behaviour).

stable: https://kallithea-scm.org/repos/kallithea/files/7f3515800bd8...

PR: https://kallithea-scm.org/repos/kallithea/pull-request -> https://kallithea-scm.org/repos/kallithea/pull-request/140/_...

(...which you can delete everything after /140/ and it works fine). Oy vey.
