    _______________________________________________________

Details:

The implementation of the groff_mdoc(7) .Lk (hyperlink) macro contains code to
make sure that the second argument is not punctuation before treating it as a
link text, but the test can never lead to the result "punctuation" because the
initialization of the global variable doc-width is missing before the call to
doc-get-arg-type.  Consequently, even "." is not recognized as punctuation:

  $ nroff -mdoc
 .Lk https://www.example.com/ .

results in:

 .: https://www.example.com/

while the correct result would be:

 https://www.example.com/.

Simple bugfix patch attached.

Problem reported by Anthony Bentley, bentley at openbsd dot org, fix by me.
