Thank you for a clarification. I always considered only vectors on LHS and RHS and I missed that one of them could be a scalar. Given this I would call:
a bug 
.
Anyway - the sooner we can have && and || broadcastable the better.
IMHO in 1.0 should be acceptable as in 0.7 everyone will get a deprecation with a clear message what will be the behavior in the future.
The practical argument for 1.0 is that I expect that with Julia 1.0 new people will consider testing it and usage of &&/|| would be one of the things that you hit when moving from other languages very early on.
