When a new version of a file is committed, Subversion doesn't always
store it as a delta against the most recent version of a file. It
uses a more complicated scheme of "skip-deltas" to minimize the number
of deltas that have to be applied to to recreate a given version of
the file. This is described in the file notes/skip-deltas in the
Subversion source distribution. My guess is that this is what you've
encountered.

Cheers,
David.
