above you're testing for > 0, not >= 0, so I think zero currently does defaultWatchCacheSize

Good spot. >=0 (= off) is correct.

@deads2k ptal. I added a possibility to inject the default value via EtcdOptions. IMO this is much cleaner than wrapping the default decorator. |

Don't we want a better way to use undecorated other than directly specifying it? @liggitt I forget exactly how we wanted to do it when I refactored this code originally.

This makes it possible to override the default watch capacity in the REST options getter. Before this PR the default is written into the storage struct explicitly, and if it is the default, the REST options getter didn't know. With this the PR the default is applied late and can be injected from the outside.
