 Adjustments to Mercurial
 
 Intentionally kept separate from `hgcompat` and `hg`, so that these patches can
 be applied without having to import the whole Mercurial machinery.
 
 Imports are function local, so that just importing this module does not cause
 side-effects other than these functions being defined.
