Regex doesn't handle colons

[craigpears]

If you type the below it fails because of the colon (which is put in by slack if you use auto complete). The regex needs to be updated to allow this optional colon after the username.

k: @user: ++

What do you mean, auto complete? I type @ tab and it doesn't put a colon in?

I do the same thing and it puts a colon in for me.
