It's a minor language quibble — don't worry about it too much. I
would suggest "disable by default," for example. "Revert" and
"backout" have a specific meaning that is approximately 'svn merge -c
-NNNNNN'.

It removes 7 lines out of 2856 lines added in the two commits. I
agree that you're technically correct — it is a partial revert. But I
think it would be more clear and accurate not to describe it as any
kind of revert, given how little (0.25% of lines) was actually
removed.

Ok, that's great. Thanks.
