shells/ksh: Fix ksh 1.0.5 Regression (issue #660)

From issue #660:

Globs are not expanded with the following:

% echo "/"{bin,sbin}"/*"
/bin/* /sbin/*

% v=/; echo "$v"bin"/*"
/bin/*

But globbing is unexpectedly performed if both parameter substitution
and brace expansion are present:

	% v=/; echo "$v"{bin,sbin}"/*"
	[output omitted for the sake of brevity]
