Please disregard this -- it's definitely not a space problem.  There appears
to be something wrong with my usage of it -- sometimes it works, and
sometimes it doesn't.  Something like this doesn't work as I would expect:

cout << BOOST_PP_STRINGIZE(BOOST_PP_SEQ_ENUM((x)(y)(z)));

But in other contexts it seems to work fine.

Also, if I replace BOOST_PP_SEQ_ENUM with the following:

#define BOOST_PP_SEQ_ENUM(seq) BOOST_PP_CAT(BOOST_PP_CAT(BOOST_PP_SEQ_ENUM_,
BOOST_PP_SEQ_SIZE(seq)), seq)

The output is "x, y, z" as  expected.
