I'm not anymore sure that this bug is worth documenting, since it is more of
a one-shot, corner-case, weirdo-looking bug rather than a more systematic
limitation or incompatibility.  What do you think?

BTW, could anyone verify whether this bug is still present in the XPG4 shell
(usr/xpg4/bin/sh) of Solaris 11 as well?  If yes, to whom should it be
reported?

Thanks,
