Bug Description

Our git importer has to differentiate between Debian and Ubuntu, so provides two separate pristine-tar branches under two separate names. This accommodates the cases where Debian and Ubuntu did not share identical orig tarballs.

We need a mechanism to specify the remote pristine-tar branch name in a build recipe, or alternatively we need a more general mechanism to create a branch locally that tracks an arbitrary remote branch.

Use case: I'm trying to combine the server team's git importer work with automatic build recipes in order to be able to automatically maintain specific deltas against Ubuntu in PPAs. The general idea is to be able to create a delta once (by branching from the imported repository) and then to leave the rest to automation. The importer will update its git repo, which will cause the build recipe to fire, merge in the pre-determined changes and build a patched version in a PPA (with a higher version than the archive).

Expected behaviour: git-build-recipe manages to find the pristine-tar branch I wish it to use, presumably by specifying it using some appropriate syntax in the build recipe.

Actual behaviour: git-build-recipe fails to find the pristine-tar branch imported by the git importer. It either fails, or if --allow-fallback-to-native is provided then it falls back by converting to a native package.

Sorry, I am not very acquinted with git-build-recipe, but is this issue the same cause as the problem I experience when trying to build a debian upstream git with a recipe: https://code.launchpad.net/~maarten-fonville/+recipe/cargo-daily

and then hitting this error:
