Hi!
Pushed with two minor changes, thanks.

I did rewrite this description to be a bit better.

And fixed these descriptions. The description for n: didn't match it at
all. For the rest I've added the switch to the string description as
well, as currently the test library is dumb and just prints the string
as it is.


It would be better to fix the library to print the swich automatically
and then fix all the tests not to include the switches in the string
description. And ideally we would pass a default value in this structure
as well...

But for now the message should include the switches otherwise it's
incomprehensible to the user.
