Subject: show-branch: fix commit naming breakage.
X-Git-Tag: v0.99.7d~1^2
X-Git-Url: https://git.octo.it/?a=commitdiff_plain;h=fbaf834de12efb43dea8d2679a040462e9d3d03d;p=git.git

show-branch: fix commit naming breakage.

It was ignoring the generation number of the commit when naming 2nd
and later parents, showing "(linus^n)^2" for any <n> incorrectly as
"linus^2".
