I added a bit to scm_c_define_gsubr about not changing the rest arg.
Existing:
If RST is non-zero, then any arguments after the first `REQ + OPT'
are packaged up as a list and passed as FUNCTION's last argument.
Add:
FUNCTION must not modify that list. (Because when subr is called
through `apply' the list comes directly from the `apply' list
argument. This list is copied when dispatching to a scheme
procedure, but not when going to a subr.)
