[svn-r13808] Description:
Fix possible file corruption when using "new" format object headers and the
size of chunk #0 for an object header transitions between needing 1->2->4->8-
byte encoding for the size and there are "clean" messages in the object header
already. (Usually triggered by flushing the file while adding attributes to
an object)
Tested on:
Mac OS X/32 10.4.9 (amazon)
Linux/32 2.6 (chicago)
Linux/64 2.6 (chicago2)
