If I write:
(defmacro test-macro () ''a nil)
(test-macro)
I get "a" as a result.
Tested with emacs -Q.
Emacs version: 24.2.50.1 (got it from development repository ~2 months ago)

This is a regression, BTW - it works correctly in Emacs 24.2.
Confirmed in this more recent version:
In GNU Emacs 24.3.50.1 (i386-mingw-nt5.1.2600)
of 2012-12-18 on MS-W7-DANI
Bzr revision: 111265 eliz@gnu.org-20121218190556-x9wmq083vwecgu0f
Windowing system distributor `Microsoft Corp.', version 5.1.2600
Configured using:
`configure --with-gcc (4.7) --no-opt --enable-checking --cflags

(macroexpand '(test-macro)) returns (quote a).
However, with something non-nil in place of nil it DTRT:
(defmacro test-macro () ''a 45)
(test-macro) ; 45
(macroexpand '(test-macro)) ; 45
