'Docs-only' forward port of 120a98120 from 1.6.x.
Fix migration autodector to work correctly with custom deconstructed values
Fixed #22558 -- Added missing word in contributing docs

So as the save step is centralized in create(), especially useful
when customizing behavior in subclasses.
Thanks craig.labenz@gmail.com for the report.
Fixed clash caused by the newly introduced -e shorthand for makemessages --exclude.
