Formatting improvements for the man page
I've changed some things to get closer to common formatting rules.
First, command options should be formatted bold in a man page. This works so far for --help and --version:
%s generates a man page out of --help and --version output.
But "%s", which expands to the command name, remains plain, but it shouldn't – it is help2man itself and should be also bold. Don't know how to reach this...
Second, the "info" in the Texinfo section, is a link to an external command. This should be a real link to the appropriate man page including section number. Not that big improvement for the terminal output, but it has an interesting side effect: HTML renderers detect this correctly and create a clickable hyperlink to that man page; see the perle(1) link in the online man page collection of Archlinux [1].
