I find it a bit underwhelming that the commit message is just "uploading " which means when looking at commit logs you can't really easily see what got uploaded.

I made a quick fix that makes it commit message like this:

micropublished article to _posts/2019-01-04-here-we-go.md

following the format:

micropublished <category> to <path>

I can submit PR with the minor change but it is for some reason not passing tests due to changed message and I haven't found an easy way to figure out how the comparison fails.
