Subject: 27.0.50; format %x and %X don't print as unsigned
Date: Fri, 8 Mar 2019 17:58:19 -0700

The following snippets return strings with negative signs, but the
docstring of format says they should be unsigned.  I get the same
results from emacs -Q as well

(format "%s_%X%X" "bob" (random) (random))
;; "bob_143E5019B284E085-3D71BF28F82AFD0"
(format "%s_%x%x" "bob" (random) (random))
;; "bob_114d97ac7a6b2a84-15fcceadc374b70e"
