Ah!  Thanks.  The light dawns.  So my test was too strict.  Can people
please try the following test instead?  This parenthesizes the ":", so

FWIW running OpenSolaris snv134, it works with bash, zsh and
/usr/has/bin/sh. /bin/sh, /usr/bin/sh (both aliased to ksh93),and
/usr/bin/ksh, all fail. Not cc'd to tar-list since I'm not subscribed.
