[PATCH][merge-tracking]Doc to justify the existence of txn_mergeinfo

From: Kamesh Jayachandran <kamesh_at_collab.net>
Date: 2006-09-27 10:32:36 CEST

Hi All,
Atlast I understood the need of txn_mergeinfo.
Attaching the patch/log that documents the same.

With regards
Kamesh Jayachandran

Patch by: Kamesh Jayachandran <kamesh@collab.net>

We cache 'txn_mergeinfo' separately to avoid looping 'paths_changed' of the txn.
