* libguile/srfi-1.h:
* libguile/srfi-1.c (scm_srfi1_drop_right, scm_srfi1_take_right): Remove
these internal functions, replacing with Scheme implementations.
* module/srfi/srfi-1.scm (take-right, drop-right): Add these impls from
the reference code. They do the right thing for improper lists,
according to the spec, but they diverge for circular lists. Oh well.
* test-suite/tests/srfi-1.test ("drop-right", "take-right"): Add more
tests.
