Slowly start implementing tagging support for man(7) pages, even

though it is obvious that this can never become as good as for
mdoc(7) pages.  As a first step, tag alphabetic arguments of .IP
macros, which are often used for lists of options and keywords.

Try "man -O tag=g as" to get the point.

Thanks to Leah Neukirchen for recently reminding me that exploring
how much can be done in this respect may be worthwhile: it is likely
to slightly improve usability while adding only small amounts of
relatively straightforward code.
