Bugfixing semantics of symbol macro hiding by variable bindings.
* eval.c (expand_vars): Expand vars needs to know whether it's
handling a sequential (let*-like) or parallel (let-like) binding.
The init form of a variable sees the previous macro environment,
but that variable must, for the remaining variables, shadow any
previous symbol macro.
(expand): In expand we must inform expand_vars whether we have
a sequential or parallel binding construct. Moreover, there was
a huge bug here: the new_menv (with the shadows) was passed to
expand_vars, so that all the variables were hiding same-named
symbol macros from all their initforms.
