Subject: Prompt user to provide at least 2 arguments rather than 3
X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=a57de3b45e7497fcdeccfd0f2194ace46c61f34d;p=ldk-sample

Prompt user to provide at least 2 arguments rather than 3

env::args returns the name of the binary, which isn't something
the end user would think about. So while we require at least 3
arguments, it makes sense to only ask for 2.
