Fix micro editor preset (#4156)

- **PR Description**

I don't know what was I thinking when making #3049, because Micro does
not actually support `--` as delimiter between options and files. As
such, when trying to edit files with `micro` set as editor, an empty
file named `--` would be open first.

This PR fixes this by explicitly defining a preset for `micro`. I've
double-tested it to make sure that it doesn't behave wierdly any more :D
