I don't know what I tested last week; most likely not the version of the
patch I quoted above.

Today's version, with the tip at 5d7f59c391ce, is definitely bogus
with its quoting. It needs the patch below, otherwise an unquoted
semicolon may be expanded from $(pathsep). This would terminate the sed
command, of course.
