I am not sure what the problem is...

At the moment rc scans ifs as a list and as a sequence of characters.
i.e., the implementation is as follows:

[from glom.c:bqinput]

        memzero(isifs, sizeof isifs);
        for (isifs['\0'] = TRUE; ifs != NULL; ifs = ifs->n)
                for (s = ifs->w; *s != '\0'; s++)
                        isifs[*(unsigned char *)s] = TRUE;

So,

	ifs='abc'

and

	ifs=(a b c)

should accomplish the same thing.

Isn't that what you want?
