This exists (because blame takes rev-list options) and works as expected (because blame.c handles this case), but is not documented. We could include rev-list-options.txt, but this wouldn't be accurate because blame does some of its own commit walking. Perhaps the following adaptation: --first-parent:: Follow only the first parent commit upon seeing a merge commit. This option can be used to determine when a line was introduced to a particular integration branch, rather than when it was introduced to the history overall.
