Sometimes you have server names with an embedded dash character (`foo.bar-baz.com`), which is perfectly valid but the previous regexp doesn't capture these cases. This PR fixes that.
Duplicate syntax definition names may cause problems.
Since nano comes with predefined all-lowercase syntax definitions,
we use uppercase letters everywhere to reduce the risk of future conflicts
The commit mariuszs/nanorc@e5cc8be863
introduced a number of rc files that cause tabs to always show as red
(even with trailing spaces). Adjust the behavior according to changes in
https://github.com/nanorc/nanorc/blob/master/mixins/lint.nanorc, which
seems to be an updated source of the original commit. Make tabs appear
green without trailing characters, red with trailing spaces, and
uncolored when followed by any other character.
