* lib.c (funcall3, curry_123_2): New functions.
(do_curry_123_2): New static function.
* lib.h (funcall3, curry_123_2): Declared.
* match.c (subst_vars): Bugfix: throw error on unbound variable instead
of ignoring the situation. This bug caused unbound variables in
quasiliterals to be silently ignored.
(eval_form): Function changed to three argument form, so that
it takes a line number for reporting errors. Restructured to catch
the new unbound variable exception from subst_vars, and re-throw
it with a line number. Also, throws exception now instead of returning
nil if itself it detets an unbound variable. Uses of eval_form
no longer have to test the return value for nil, but just assume
it worked.
(match_lines): Currying calls to eval form updated to use
curry_123_2. Test of eval return value eliminated. In function
calls, eval isn't used for reducing symbol arguments to values,
because it now throws in the unbound case, and it's not worth
setting up a catch for this. Instead, assoc is used directly.
