consider
	awk '/'^(a b)^'/' /dev/null

	awk: can't open file /b/
	 source line 1

your case is similar:

	T=(a b)
	awk '/'^$T^'/' /dev/null

	awk: can't open file /b/
	 source line 1

and finally

	awk '/'^$"T^'/' /dev/null

success?  note the " before the T in the last one.

I think this is a problem with rc treating $T as a list, and you need
a list flattening operator (double quote).

Perhaps what you need is 

awk '/'^$"T^'/' all.uniq
