Thanks for the handy answer, Ingo.
I am going to develop it better.

I assume what you mean is that you could, but the "-O tag" option had
no effect.
because lynx and links can't accept the /tmp/man.XXXXXX... file as
an URL...
In "-T html" output mode, the tag file isn't even written in the first
place. Only the terminal formatter writes a tag file.
then I decided to add a new parameter (-U)
Absolutely not. Adding new options to man(1) is completely out of
the question. Option space is almost full and very messy already:
https://mandoc.bsd.lv/man/man.options.1.html
It hardly matters that -U is already taken:
https://mandoc.bsd.lv/man/man.options.1.html#U
You certainly can't take an option that is still free for this
purpose, either.
to pass the pager a formal file URL scheme as follows:
file:///tmp/man.XXXXXXX#tag
Then man spawns the pager (lynx for my case):
lynx -force_html file:///tmp/man.XXXXXXX#tag
That's an interesting idea.
It needs to be done by default when -T html -O tag is given, just
like tagging is enabled by default when the pager is less(1).
The testing command is:
PAGER="" MANPAGER="lynx -force_html" ./man -U -T html -O tag=k pfctl
The PAGER="" variable has no effect when MANPAGER is set,
see the man(1) manual.
So the goal is to make this work:
MANPAGER="lynx -force_html" ./man -T html -O tag=k pfctl
Sorry, I didn't reviewed the code well. The first diff has some bugs.
As follows the stable diff (please, review):
I didn't review the diff closely, yet.
Obviously, using strncpy(3) or strncat(3) is not permitted,
but those should be easy to replace, perhaps with mandoc_asprintf(),
not sure yet.
It looks like you will have to pass outst into run_pager() and
spawn_pager() rather than outst.tag_files, such that you can check
for outst.outtype == OUTT_HTML inside spawn_pager().
In any case, thanks for the nice idea!
Yours,
Ingo
