merge-recursive: fix the diff3 common ancestor label for virtual commits
In commit 743474cbfa8b ("merge-recursive: provide a better label for
diff3 common ancestor", 2019-08-17), the label for the common ancestor
was changed from always being
"merged common ancestors"
to instead be based on the number of merge bases:
>=2: "merged common ancestors"
1: <abbreviated commit hash>
0: "<empty tree>"
Unfortunately, this did not take into account that when we have a single
merge base, that merge base could be fake or constructed. In such
cases, this resulted in a label of "00000000". Of course, the previous
label of "merged common ancestors" was also misleading for this case.
Since we have an API that is explicitly about creating fake merge base
commits in merge_recursive_generic(), we should provide a better label
when using that API with one merge base. So, when
merge_recursive_generic() is called with one merge base, set the label
to:
"constructed merge base"
Note that callers of merge_recursive_generic() include the builtin
commands git-am (in combination with git apply --build-fake-ancestor),
git-merge-recursive, and git-stash.
