histedit: narrow the scope of discarded ui output
In 34165875fa5df813bec3a0cd348932b304d44efb, a lot of the output from
histedit was excluded. This slightly adjusts the scope of that exclusion,
to both discard more uninsteresting messages, and ensure that pre-merge-tool
output gets shown before the external merge tool is executed.
