I first tried the obvious, "checkout the current branches files for these":
git checkout file1 file2 file3
No, that didn't work:
error: path 'file1' is unmerged error: path 'file2' is unmerged error: path 'file3' is unmerged
Well, yeah I know that and I Don't Care, checkout the files ¤!#"f*!!%"# stupid git!
After googling around I finally found the solution in this old post.
git checkout HEAD file1 file2 file3
