40305: fix some problems redisplaying command line after interrupt.

Back off previous fix as this only covered some subset of problems.

Remaining problems happend after reset-prompt in TRAPINT.

One was in complist and is fixed by not attempting to list after
an error or interrupt.

The other was owing to not resetting clearflag when ZLE
was re-entered.
