Hello,
We already have `--with-branch=`, `with-commit=`, ... An additionaloption could be `--with-patch=package=add-extra-feature.patch` whichwould apply the patch file `add-extra-feature.patch` located in the mycurrent directory to the sources of `package` before Guix startsbuilding `package`.
This would bring the possibility to easily share patches (for tests,reviews, ... for instance) without having to commit the patch in thesource repository of the package, without changing the packagedefinition, and without applying ourselves the patch to our local sourcerepository of the package.
Thanks !

Good idea! The patch below does that.
Feedback welcome. :-)
