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?
Byron.
