Subject: merge-recursive: make the error-message generation an extern function
X-Git-Tag: v1.6.6-rc1~9^2~1
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=264b774ba6b27cc07ef4c33d52e491d9abf029bb;p=git.git

merge-recursive: make the error-message generation an extern function

The construction of the struct unpack_trees_error_msgs was done within
git_merge_trees(), which prevented using the same messages easily from
another function.

[jc: backported for 1.6.5 maint before advice_commit_before_merge]
