Fix all hyphens errors detected by yamllint:
yamllint -f parsable -c .yamllint $( find -regex '.*\.y[a]*ml' ) | \
grep '(comments)'
Default config would be to require two spaces after the start of the
comment, proposing to keep it on 1, inline with the Linux binding
config, that is:
```
- comments:
- min-spaces-from-content: 1
```
