branch --bind or branch --bound?

[Ian Clatworthy]

Eli suggested my proposed --bind option for branch be called --bound
instead. I don't mind either way. What would new users expect the option
to be called?

Is it:

* --bind (because branch --bind == branch + bind), or
* --bound (because it creates a bound branch)?

I don't want to bikeshed on this but I'll give it 18-24 hours before
making a call.
