Subject: Use 'merge-base --all' where applicable.
X-Git-Tag: v0.99.9g^2~1
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;ds=sidebyside;h=13956670a7baf4b3b794a2cc799bd501753f1746;p=git.git

Use 'merge-base --all' where applicable.

It may get extra merge base on truly pathological commit histories,
but is a lot easier to understand, explain, and prove correctness.
