Yes, that's because I copied them from Draft #1 after the global
replacement of "span" with "string".  Fixed.

R7RS-small has both.  I think of `substring`, which is the only name in
R5RS, as primarily for backward compatibility.  On the other hand, there
is no contrast between -copy and -copy! here, as there is in R7RS-small
and SRFI-13.

(In SRFI 13, string-copy makes a real copy, whereas substring may make
a shared substring, but this distinction matters only in Guile.)
