summary: merge: fast-forward merge with descendant
Before named branches, the invariants were:
a) "merges" always have two parents
b) p1 is not linearly related to p2
Adding named branches made (b) problematic, so the above patch was
introduced, which fixed (b) but broke (a).
After discussion, we decided that the invariants should be:
a) "merges" always have two parents
b) p1 is not linearly related to p2 OR p1 and p2 are on different branches
