Junio C Hamano 0290bf1250 Revert 4b7f53da76 (simplify-merges: drop merge from irrelevant side branch, 2013-01-17)
Kevin Bracey reports that the change regresses a case shown in the
user manual.

Trading one fix with another breakage is not worth it.  Just keep
the test to document the existing breakage, and revert the change
for now.
