[CI:DOCS] fix go-md2man HTMLSpan warnings

I'm tired of seeing these every time I run 'make':

   WARNING: go-md2man does not handle node type HTMLSpan

Cause: left-angle-brackets ( < ) in document source

Solution:
  1) backquote-escape those that need to be shown, usually
     ones referring to an argument or email address; or
  2) Actual HTML ( <sup> and <a> ) which are meant to be
     shown in generated HTML docs but can't be shown in
     man pages, we filter out via a sed expression.
