This is incorrect. The gzip_static assumes there are two files
with identical contents:

foo
foo.gz

The "foo" file (uncompressed one) will be returned to clients
which doesn't support gzip. The "foo.gz" file (compressed one)
will be returned to clients which support gzip.

If you want nginx to uncompress a gz file, you have to use
recently introduced gunzip module, see http://nginx.org/r/gunzip,
along with gzip_static set to "always".

I'm not sure I understand correctly what you want, but it looks
like what you are asking for is "gzip_static always", as available
in nginx 1.3.6+. See http://nginx.org/r/gzip_static for details.
