w3mman incorrect query string

[memreflect]

w3mman 7z fails because it generates ?quit=ok&section=7z.
w3mman 1 7z generates ?quit=ok&section=1&section=7z.
w3mman foo bar incorrectly generates ?quit=ok&man=foo&man=bar.

Since the syntax is [[section] page], this is incorrect. One possible fix is to use Getopt::Std, which has been standard since the early days of Perl 5. Another alternative is to limit the number of sections to 1 (e.g. /^\d/ || ... ⇒ $query !~ /&section=/ && (/^\d || ...) will fix the w3mman 1 7z case) and to detect an incorrectly generated query string after the loop (i.e. ?quit=ok&section=7z should be changed into ?quit=ok&man=7z).
