the entry for "\e\t" from input-decode-map.

ce04647d4d Revert "Remove PROBLEMS section on double-buffering"
This reverts commit 366b2bc757.

We cannot be sure this problem is no longer relevant, since
its root cause was in software we don't control, and cannot
tell whether any of the versions where that problem happened
are still out in the wild.
