Interesting.  I hadn't tried '-I' but now also see that.

I would also welcome any insights jilles@ can offer.

pfg@ (who shepherded the libedit update into the tree), David Shao
(originator of kern/169603) and I have been investigating fixes to
libedit but do not have a solution yet.  There is a possibility that
sh(1) is relying on bugs in the old libedit.

At this stage, it seems likely that the libedit update (r237738)
will be reverted for 9.1-RELEASE.
