[MERGE] branch.has_explicit_nick

[Robert Collins]

I think its useful to discriminate between explicit and implicit nick
setting:

If this looks reasonable, I'll add an explicit test for it. (I have an
explicit test already where I wrote the code, but I didn't put it
against Branch. I'm now cleaning that code up, and factoring this onto
branch.)
