Nope. The manual says that AS LONG as both sides are wrapped by double
quotes, then there is NO problem. The problem exists for things like:

	if [ $VALUE = test ]

if $VALUE is null, then the shell will barf. There are 2 methods to avoid

	if [ x$VALUE = xtest ]


	if [ "$VALUE" = "test" ]

See above and below. Most use only one or the other. Perl uses
'test "X$var" = "X$val"

See above. Using "x-flag" is NOT required, but is SIMPLY for
extra insurance. If we want to use this UNIVERSALLY then I am ALL
FOR IT. In fact I would PREFER it and HAVE suggested it.

At which point it will be caught and fixed...

Note that I was the one who ORIGINALLY did the "x$var" = "x" stuff
and that THAT was changed and altered to all forms of this method.
At least now, if we want to do it RIGHT, we can simply change
[ "$var" = "whatever" ] to [ "x$var" = "xwhatever" ] RIGHT NOW.
Reversing back to what we had DOES NOT make things better. If you
are against the present method, fine, but then let's do it CONSERVATIVELY

Before you back that out, how does that fly?
