Thank you, @lkxed !
This is looking great, but instead of creating two new files, would you mind adding your code to the existing repos_merging.go and repos_merging_test.go files?
I think both are small enough and related enough to live in the same file.

Hi, @gmlewis . I have moved my code. :)

[gmlewis]

Thank you, @lkxed !
Just one minor renaming tweak, please, then I think we will be ready for a second LGTM before merging.

[lkxed]

@gmlewis I have changed the names. :)

[gmlewis]

Thank you, @lkxed !
LGTM.

Awaiting second LGTM+Approval from any other contributor to this repo before merging.
