`CAP REQ SASL` expects a space?

[slingamn]

I got a bug report that matrix-appservice-irc wasn't correctly connecting to oragono with SASL. I think the culprit is this line:

node-irc/lib/irc.js

Line 663 in 7feccae

message.args[2] === 'sasl ') // there's a space after sasl

I'm not sure where the expectation came from that there would be a space after 'sasl', but I'm pretty confident that it's incorrect to require this.

Thoughts? Thanks for your time.
