My test above was done on a Debian box with a fairly up-to-date Etch
distribution, using GNU grep 2.5.1 and GNU bash 3.1.14(1)-release.
A test on a Solaris 10 box with up-to-date patches, using Solaris grep
(both /usr/bin/grep and /usr/xpg4/bin/grep) and ksh (M-11/16/88i)
produced the same successful results. At the moment, to me, it looks
to me like a bug in GNU grep that Debian patched.
