vm-edit-message for re-threading

[Uday Reddy]

If you use vm-edit-message to add "In-Reply-To" and "References" headers and put the message inside an existing thread, it appears that the cached data has inconsistencies.

The summary buffer showed the message in the correct place. However, doing `vm-next-message' took me to the old successor of the message, not the successor in the new message-order.

Perhaps other parts of the cached data also have inconsistencies.

I could not reproduce this when I tried to switch around message IDs in References fields in an existing thread. Navigation in the summary always followed the thread order in the summary buffer (with vm-summary-show-threads on).

In another test case, however, adding a 'References' to an otherwise unthreaded message put it into a short 2 message (now 3) thread in the right place (and navigation worked). But when I removed the artificial 'References' header, the message did not lose its thread indentation until I quit the folder and re-entered. Toggling vm-summary-show-threads off then on didn't help. Also note that vm-discard-cached-data did not help here. Does it help your failure case?
