* scheme-compound.texi (Append/Reverse): Merge reverse and reverse!,
describe newtail parameter for reverse!, remove confusing caveat about
head becoming tail for reverse!.
(And I think the docstring for reverse! can be modified similarly.)
- Scheme Procedure: reverse lst
- Scheme Procedure: reverse! lst [newtail]
- C Function: scm_reverse (lst)
- C Function: scm_reverse_x (lst, newtail)
Return a list comprising the elements of LST, in reverse order.
`reverse' constructs a new list, `reverse!' modifies LST to
construct its return.
For `reverse!', the optional NEWTAIL is appended to to the result.
NEWTAIL isn't reversed, it simply becomes the list tail. For
`scm_reverse_x', NEWTAIL is mandatory, but can be `SCM_EOL' if no
further tail is required.
