Will it also properly quote all the strings in whichever script it was
that caused us tons of problems the last time we tried using libtool
1.4[.x]?  (I forget whether it was ltconfig or not, but the one release we
built using libtool 1.4[.x] failed to build on a number of platforms
because the script in question bombed out with a syntax error because
some variable was either unset, or set to a null string, and they were
doing a test something like

	if test $foo = bar

which doesn't work if "foo" isn't set or is set to a null string;

	if test "$foo" = bar

works, as does

	if test X$foo = Xbar

and as does

	if test "X$foo" = Xbar

.)
