This includes the following changes:

* Reduce inline comments that were mostly redundant to the code it
described

* Added another example to the man-page to make clear that TLS is
supported for CNAMEs. For that matter, all other options will also work
without change, given that internally the CNAME will only be resolved to
an FS-ID before handing back over to the same logic that is already in
place.

* Small modifications to better adhere to the given codestyle.

* Adjusted log messages as suggested.
