Is your feature request related to a problem? Please describe.
I am currently setting up an automatic Github actions coverage-report system, where I want to automatically create a GitHub page where I can see my coverage report. Doing that though, I encountered an issue with the coverage html command where the result HTML-files have a leading underscore making them private in the eyes of GitHub and so not visible.

Describe the solution you'd like
Remove the underscore if possible, since I don't expect it to have big importance or requirement to be that way

Describe alternatives you've considered
Contacting GitHub / opening an issue, but that would require a lot more change, which is why I am requesting here to possibly change it
