document and fix findincoming - add documentation about what the function does, notably the fact that it updates 'base' - transform the workflow to a more simple 'if elif elif else' - do not call remote.branches if not necessary - some nodes where missing in 'base' (from what I understand, if the root of a branch is missing but one parent is present, the parent should be in 'base') - add a testcase for an incorrect outgoing that is fixed by this cset - add a testcase for an empty group bug, it needs fixing
