I installed libedit_3.1-20150325.orig.tar.gz from source here, and it
passes our current regression test and seems to behave just fine in
light manual testing.  (I did not apply any of the Debian-specific
patches at [1], but they don't look like they'd explain much.)
So I'm a bit at a loss as to what's going wrong for you.  Is the test
environment for Xenial the same as for the other branches?
