While dumping files using wt verify -d dump_pages or similar the txnids will be cleared by the call to __cell_unpack_window_cleanup in cell_inline.h. This can be a bit frustrating as the transaction ids can be helpful when diagnosing a crash / failure.

We should add a flag or similar to WiredTiger that tells the cell unpack code to not clear the txnids. This flag should then be enabled with a new command line option passed to wt verify.

Scope:

• Investigate and implement adding a new flag to WiredTiger to turn off cell window cleanup.
• Add a new command line option to the wt verify utility to turn on the flag.
