@var{lst} should be a list (@var{arg1} @dots{} @var{argN}
@var{arglst}), with @var{arglst} being a list. This function returns
a list comprising @var{arg1} to @var{argN} plus the elements of
@var{arglst}. @var{lst} is modified to form the return. @var{arglst}
is not modified, though the return does share structure with it.
This operation collects up the arguments from a list which is

/* This code processes the arguments to apply:
(apply PROC ARG1 ... ARGS)
Given a list (ARG1 ... ARGS), this function conses the ARG1
... arguments onto the front of ARGS, and returns the resulting
list. Note that ARGS is a list; thus, the argument to this
function is a list whose last element is a list.
Apply calls this function, and applies PROC to the elements of the
result. apply:nconc2last takes care of building the list of
arguments, given (ARG1 ... ARGS).
Rather than do new consing, apply:nconc2last destroys its argument.
On that topic, this code came into my care with the following
beautifully cryptic comment on that topic: "This will only screw
you if you do (scm_apply scm_apply '( ... ))" If you know what
they're referring to, send me a patch to this comment. */
