--bind option doesn't accept interface name

[bam80]

It's more like a feature request, because now I have to write tricky scripts to get IP address of the interface, instead of just passing it by name in the -B option

We note this is a little tricky because an interface can have multiple IPv4/IPv6 addresses and picking the right one might be hard.

This at least requires getting the right protocol family from specified server (-c). Maybe I did it already in my local branch...

[bam80]

Can this feature be implemented at least for the case when an interface has only one IP address? It is far more convenient and straightforward to specify interface by name

This is not likely to happen for reasons I cited above, but #1089 and #1097 are somewhat related to this.
