doc/gen-man.sh: head and tail +/- syntax is not portable 

the + and - syntax on head and tail are only present, as far as i know,
in GNU coreutils, and are not present on any other UNIX or BSD systems.

this patch replaces those with a more portable processing chain, which
is tested to work on GNU coreutils, NetBSD, macOS, and busybox.
