I have another batch waiting to be assembled into patches, mostly patches
I've already posted to the mailing list.

Hi Chet, what kind of bug fixes can we expect to be backported to the
current release branch (4.4)?

Thanks for the report. This was fixed last month after a report from back
in November. The fix is in the devel branch.

That looks like the same issue as this one from November:
Subject: foo=$*: ^A and DEL are prefixed or removed
http://lists.gnu.org/archive/html/bug-bash/2017-11/msg00107.html

If I read the commit message correctly, this looks like a fix for it:

Confirmed (with default IFS; it is important to note that).  And also
for the record, v="$*" gives the expected result.

wooledg:~$ v="$*"
wooledg:~$ printf '%q\n' "$v"
$'\001'

Just another case of "never ever EVER use unquoted $* or $@", for us
script writers.  Chet may still choose to address it as a bash bug,
of course.
