This part is now fixed, too, see the commit below.

The guesswork required to deal with .IP certainly isn't perfect yet,
but lets walk one step at a time, and let's start with issues that
actually cause inconvenience in real-world manual pages.

Yours,

Log Message:
-----------
Support the GNU-specific syntax ".IP \\[bu]" for bullet lists in man(7) 
pages that Alejandro Colomar recommends in the "Lists" subsection of
https://man7.org/linux/man-pages/man7/man-pages.7.html#STYLE_GUIDE .

For example, this will improve HTML formatting of the first list in 
the subsection "Feature test macros understood by glibc" on the page
https://manpages.debian.org/bookworm/manpages/ftm.7.en.html .

Issue reported by Alejandro Colomar <alx at kernel dot org>.
