Right. The only SRFI-1 procedures added to R7RS-small are `make-list` and
`list-copy`, based on the corresponding vector and string procedures. In
addition, some others were slightly changed for SRFI 1 compatibility: e.g.
R7RS-small `map` is specified to stop when one of the list arguments is
exhausted, whereas in R5RS it was an error to provide lists of different
