4739: Allow retroactive creation/editing of RB revision ("change") description ("text")


What version are you running?


What's the URL of the page this enhancement relates to, if any?

Describe the enhancement and the motivation for it.

I would like to be able to add or modify a change-description after the fact (e.g. if I forget to write one before publishing the change).

By change I mean an review-request revision not the review-request itself (whose description can already be edited). I.e. the "text" field of a change entity as in https://www.reviewboard.org/docs/manual/2.5/webapi/2.0/resources/change-list/#webapi2.0-change-list-resource

What operating system are you using? What browser?


Please provide any additional information below.

This would be zhweeeet :D
