The command line
	{ sleep 3 ; /bin/echo foo } &
gets parsed as
	sleep 3 ; /bin/echo foo &

under bash 1.04 on our machines here.  /bin/sh interprets it as
	( sleep 3; /bin/echo foo ) &
if a semicolon is placed after "foo" (and passes "}" to echo
otherwise; i.e., "}" must come first on the command line to have its
meaning as a grouping symbol).

I'd like to congratulate Bill for always coming up with the most interesting
bugs.  This one took a while.

The problem is not the parsing, but the execution (that is, the line is
parsed correctly, but the execution of group commands discards this kind of
background information).  I have sent a fix to Brian.
