[B.A.T.M.A.N.] [PATCHv2] batctl: man page - fix undefined macro warning

[Marek Lindner <lindner_marek@yahoo.de>]

A line beginning with ' or . in a groff file has a special meaning and
cannot be used for literal text. Instead the interpreter will try to
execute it and fail doing so. A zero-width space or reformatting the
paragraph can be used as simple workaround.

This problem was detected using: LC_ALL=en_US.UTF-8 MANROFFSEQ=''
MANWIDTH=80 man --warnings -E UTF-8 -l -Tutf8 -Z man/batctl.8
>/dev/null

 v2:
     * Use different approach to solve issue as first attempt was too
       obscure.

 If no parameter is given the current gateway mode is displayed otherwise the parameter is used to set the gateway mode. The
-second (optional) argument specifies the selection class (if 'client' was the first argument) or the gateway bandwidth (if

 this node's internet connection bandwidth. Just enter any number (optionally followed by "kbit" or "mbit") and the batman-adv
 module will guess your appropriate gateway class. Use "/" to separate the down\(hy and upload rates. You can omit the upload
 rate and the module will assume an upload of download / 5.
