#4439 enhancement closed fixed (fixed)

Documentation: clarify that callback() may return before callback chain is complete

This ticket simply requests that documentation for the callback and errback methods of twisted.internet.defer.Deferred clarify when they will return. As currently written, a programmer might assume that these methods will not return until the chain has completed. In fact, the methods will return as soon as they run into a Deferred-returning function in the chain. 'course, it's probably best to provide no guarantees as to when these functions will return in case the Twisted implementation changes.

Very minor nit: *error*- callback should be *error*-callback. Everything else looks good, please merge.
