[PATCH BlueZ v3 5/5] client: prettify help table

[Lucas De Marchi <lucas.demarchi@profusion.mobi>]

From: Lucas De Marchi <lucas.demarchi@intel.com>

cmd + options have a maximum length of 25. Align the description
after this value. In order not to reach 80 chars so easily change the
first \t to 2 spaces, like is done in udev, kmod, systemd, etc.
