One of those bugs at least causes the wrong options for yodl to
be used and "-s" (strip) to be used.

$ posh -c 'case abc in *"b"*) echo yes; esac'
$ posh -c 'case abc in *b*) echo yes; esac'
yes

The patch below works around those, but it still doesn't build
with posh. I'd tend to agree it's probably not worth the effort
working around those if posh is no longer maintained.
