Description blah 2006-08-12 15:03:06 UTC
I'd like to suggest adding a 3-way diff feature that runs a diff3 between three
revisions of a page, e.g.

The purpose is to assist reverting an arbitrary edit, e.g.:
  1. Spammer inserts spam extlink into article
  2. Other people edit the article, leaving the spamlink in place
  3. You want to remove the spamlink leaving the later edits in place.

The diff3 feature would allow putting an command into navpops that would diff3
the spam edit, the previous edit, and the current version, then edit out the
spam.  There could also be a "revert" button attached to every diff in a history
list, as an enhancement to admin rollback.  There's a little more discussion of
this on Lupin's talk page and the server-side diff3 was his suggestion:

Comment 1 blah 2006-08-12 15:04:30 UTC
I should add: the diff3 output should be XML, for easy digestion by navpops and
similar tools.
Comment 2 Rob Church 2007-06-09 15:56:04 UTC
We more or less have this, in the form of the "undo" feature.
