scale.nice should be sticky, like scale.round?

[mbostock]

Currently, scale.nice only modifies the scale’s current domain; if you set a new domain, it won’t be niced. However, perhaps scale.nice should function more like scale.round, and remember the nice setting, such that any new domain that is set is automatically niced.

However, this would not be a backwards-compatible change, since it would affect the behavior of scale.nice() with no arguments: it would now return the current nice count, which would default to undefined indicating that the scale is not niced.
