    ugh.  that makes Ref*() -- which use CONCAT -- really ugly.
    i'm beginning to regret promising reiser cpp support.

    oh well; probably fixed in 0.75, but i don't like it.

another thing to make your hair stand on end: the following line

	assert(streq(t->CAR->u[0].s, "%heredoc"));

doesn't work with -DREISER_CPP. the problem is the STRING macro:

#define STRING(s)      "s"

#define assert(expr) \
        if (expr) ; else { \
                eprint("%s:%d: assertion failed (%s)\n", \
                       __FILE__, __LINE__, STRING(expr)); \
                ABORT(); \
        }

heredoc.c is the only place where it happens.
