* lisplib.c (arith_each_set_entries): Trigger autoload on
new symbols.
* stdilb/arith-each.tl (sys:arith-each): Generalize macro to
handle short-circuiting logical operations. The op-iv
parameter, which is a cons, is spread into two op and iv
parameter.
One new argument appears, short-circ. This specifies a code
for short-circuiting behavior: t means iteration continues
while the result is true; nil means it continues while it is
nil, and + means iteration continues while the accumulator is
nonzero. A new convention is in effect: the operator has
to be specified as a list in order to request accumulating
behavior, e.g (+) or (*). Otherwise the operator specifies a
predicate that is applied to the forms, without taking into
account the prior value.
(sum-each, sum-each*, mul-each, mul-each*): Spread the op-iv
arguments. Wrap the op argument in a list to request
accumulation. In the case of mul-each and mul-each*, specify +
for the short-circ argument, which means that iteration stops
when the accumulator becomes zerop. sum-each and sum-each*
specify : for the short-circ argument which is unrecognized,
and so ther is no short-circuiting behavior.
(each-true, some-true, each-false, some-false): New macros.
* tests/016/arith.tl: New tests.
* txr.1: Documented new macros and added note about possible
short-circuiting in mul-each and mul-each*.
* stdlib/doc-syms.tl: Updated.

* stdlib/arith-each.tl (sys:arith-each): If there are no vars,
then just reduce to the identity element value.
This is alreading happening fine for the each-prod family
of operators.
* tests/016/arith.tl: Test cases covering the no vars
and empty iteration identity element cases for sum-each and
mul-each, as well as the *-prod variants.
* txr.1: Document empty iteration and empty vars behavior
for arithmetic each operators as well as the each-prod
family.

* tests/common.tl (sstest): New macro. Like stest, but the right hand
side is an object which the macro turns to a string, rather than
expecting a string.
* tests/016/arith.tl: Use the sstest macro for the main quantile
test to compare the result and expected value as character strings
rather than objects. Specify the expected values using no more
than 14 decimal digits of precision, and over the scope of the test
case, restrict floating-point printing to 14 digits. Thus, we
effectively have quick and dirty epsilon comparison to 14 digits
that recurses over the list, without having to write that as a function.

* arith.tl: Somehow I committed some wrong expected numbers in
a quantile test, yet didn't catch the test failure.

* lisplib.c (arith_each_instantiate, arith_each_set_entries): New
functions.
(each_prod_set_entries): Add sum-each-prod, sum-each-prod*,
mul-each-prod and mul-each-prod* as autoload triggers for
each-prod.tl, where those macros are now defined.
(lisplib_init): Register autoloading of arith-each.tl via the
two new functions.
* stdlib/arith-each.tl: New file.
* stdlib/each-prod.tl (sys:expand-each-prod*): Handle sum-each-prod* and
mul-each-prod* in the same way, by mapping to their parallel binding
counterparts.
(sys:expand-arith-each-prod): New function.
(sym-each-prod, mul-each-prod, sum-each-prod*, mul-each-prod*): New
macros.
* tests/016/arith.tl: New tests.

The issue, reported by Paul A. Patience, is that
code like (< 1 "abc") is successfully producing a result.
The root cause is that 1 is an iterable object, and so
is treated as a sequence opposite to the "abc" operand.
We should allow only true sequences in this situation.
* arith.c (seq_lt_compat_check): New static function. Checks
that neither of two sequences is SEQ_NOTSEQ or SEQ_HASHLIKE.
(seq_lt, seq_le): Use seq_lt_compat_check to reject dubious
inputs.
* txr.1: Minor wording change in the related documentation,
removing a gratuitous adjective.
* tests/016/arith.tl: Inequality tests.

* arith.c (nary_op_keyfun): Static function removed.
(nary_op_seq, nary_op_seq_keyfun): New static functions.
(sumv, prodv): Static functions removed.
(sum, prod): Reimplement using nary_op_seq and
nary_op_seq_keyfun. Conversion of sequence to
list smuggled via args is gone.
* tests/016/arith.tl: new sum and prod tests.
* txr.1: Note about sum and prod taking an iterable sequence
added.

negative two's complement integer, #x-800...00 in various
sizes. The 64 bit cases are failing.

* tests/016/arith.tl: Add tests covering the fixnum/bignum
knee, and ffi operations of various sizes that provide
coverage of various conversion routines.

Reported by user vapnik spaknik.
* lib.c (bracket): Don't rely on the index variable to step
through the arguments, because it only counts fixed arguments.
The args_get function doesn't increment the index beyond
args->fill; when popping arguments from args->list, index
stays unmodified.
* tests/016/arith.tl: Tests for bracket added.

tests/016.
