In -T locale (the default), -T ascii, and -T utf8 mode, provide a new
output option -O tag[=term] to move right to the definition of "term" when
opening the manual page in a pager, effectively porting the -T html
fragment name feature - https://man.openbsd.org/ksh#ulimit - to the
terminal. Try:
$ man -O tag uvm_sysctl
$ man -O tag=ulimit ksh
$ man -O tag 3 compress
Feature development triggered by a question from kn@. Klemens also
tested, provided feedback that resulted in improvements, and provided
an OK.
