Subject: [PATCH] com_help(): Improve formating of command/description list

The help output, which consists of the subcommand name and the
one-line description, is formatted incorrectly if the name of one
or more subcommands exceeds 16 characters. Pre-compute the maximal
length of the command names upfront to fix that.
