Thanks a lot for reporting!

I think our alias implementation is quite custom and I wonder if clap can do more for us to be less surprising. CC @schacon as original author, and maybe @slarse if this would be interesting to dabble in.

I have beef with the parsing there, putting this on my TODO list and taking a look as soon as I can. Probably not this week, if someone is faster to the punch feel free to just yoink this issue. I'll assign myself when I get around to this.
