Here's the exact scenario:
1. Block r10 from merging from branch A -> branch B
2. Merge changes from branch B -> branch C.
3. Merge changes from branch A -> branch C.

Should (3) attempt to merge r10 from branch A -> branch C? This
depends on whether the block of 'r10' is merged when you merge from
branch B -> branch C.

Cheers,

David
