[whatwg] Terminology: managed vs. manual transactions

[Aryeh Gregor]

In the UndoManager spec <http://rniwa.com/editing/undomanager.html>,
there are two types of transactions: managed and manual.  Managed
transactions are handled by the browser, while manual ones are handled
by the author.  The term "managed" keeps confusing me, though.  I
never remember if it means managed by the browser, or by the author.
Why don't you rename managed transactions to "automatic transactions"
or something like that?
