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.
