Hyperlinks in Terminal man pages

Question

Several third party applications (eg ManOpen) put hyperlinks in man pages. Often this is done on the fly using the same man page source as the Terminal.
Does Apple do this with the Terminal or any other applications which use local (ie not web) man pages?
My groff_mdoc man page says:
      .Lk To be written
but a more informative description at http://www.daemon-systems.org/man/mdoc.7.html says:
      .Lk link (for conversion to HTML). Usage: .Lk <href> [anchor-text]
I suspect Lk has not been widely used and that third party applications probably use the existing Xr tags about which my groff_mdoc man page says:
Manual Page Cross References
      The '.Xr' macro expects the first argument to be a manual page name. The optional second argument, if a string (defining the manual section), is put into parentheses.
      Usage: .Xr ⟨man page name⟩ [⟨section⟩] ...
        .Xr mdoc        mdoc
        .Xr mdoc ,      mdoc,
        .Xr mdoc 7      mdoc(7)
        .Xr xinit 1x ;  xinit(1x);
      The default width is 10n.
Is it possible to get the Terminal to use these existing Xr tags as hyperlinks?

Answer 1

Sorry, I didn't peruse that link. On my machine, man:<commmand> works in Safari.
Thanks for that I had misread the instructions and tried man: ls and man ls (as per terminal) rather than the correct man:ls
That's incorrect. This example is from the chmod manpage:
+     The -H, -L and -P options are ignored unless the -R option is specified. In addition, these options override each other and the command's+
+     actions are determined by the last one specified.+
In my terminal I get the following:
Case 1 - Terminal/Prefences/Window Columns set to 80
The -H, -L and -P options are ignored unless the -R option is specified.
In addition, these options override each other and the command's actions
are determined by the last one specified.
Case 2 - Terminal/Prefences/Window Columns set to 120
The -H, -L and -P options are ignored unless the -R option is specified. In addition, these options
override each other and the command's actions are determined by the last one specified.
For these tests I closed Preferences and then opened a new Terminal window. Manually widening the windows did not increase text width further but narrowing them resulted in an untidy soft text wrap a character at a time rather than the normal word at a time.
Am I the only one with a Terminal that does this or does it work for others?
