Thank you @olirwin!

The tests failed, can you fix them?

Thank you @olirwin!

The tests failed, can you fix them?

Fixed as much as I could understand (there were 2 failing tests, one due to linter warnings, the other to test coverage). I am not in a position to write tests for this change in code.

The other tests were just being auto cancelled.

Solved this: add support for files with no extension #577 and: Fixes Icons for files without extenstions #459 Relates to Icons for file with only one extension #469

tests:

bundle exec rubocop
bundle exec rspec
test/run

finished OK

Here you can see dot-files with icons and file without extension with icon, and also can be file only from dots:

how to assign it to me ? and make me permission to commit branch and PR ?
