Hi All,
One more observation on bdb structure doc. Find the attached patch.
I could not see REP-OFFSET (part of WINDOW which is part of
REPRESENTATION DELTA KIND-SPECIFIC)implemented in subversion yet.
Shall we mention the same in the doc.
With regards

one string. This is so we can replace a string with deltified version
of itself, change the representation referring to it, and know that
-we're not messing up any other reps by doing so.
