This option list was tabbed over 19 characters. style.mdoc(5) asks
that lists are set to the longest item, or if that's too long then
to use indent. Resetting it to indent buys us two lines at MANWIDTH
80, and three at 59.

* Add a small description before the EXAMPLES that are already in the man page
to explicitely state what we are trying to show instead of having the user
guess what the example is doing.
* Add two more examples to show usage of -s, -t and -f
* mandoc -Tlint reports irrelevant use of .Tn so remove them since according to
mdoc(7) it is there only for compatibility and should not be used in new
manuals.
