Sorry, I'm not following.

So, I just created an artificial conflict. Then I get these errors:

    λ git merge -X theirs
    error: Merging is not possible because you have unmerged files.
    hint: Fix them up in the work tree, and then use 'git add/rm <file>'
    hint: as appropriate to mark resolution and make a commit.
    fatal: Exiting because of an unresolved conflict.
    λ git add -u
    λ git merge -X theirs
    fatal: No current branch.
