instances of 64-bit arithmetic were costing 775 bytes, and the
inlining offered no benefit. Moreover, ambiguity as to the argument
types led to the introduction of a bug (see rev 1.56).
Also, remove some casts that are now clearly redundant.

Note that `ps t' is still changed to `ps -T', since that is one of
the main reasons for this kludge processing...

more special situations. This is the code which process `ps blah',
when "blah" does not include a leading '-'.
This change also removes a long-undocumented BACKWARD_COMPATIBILITY
compile-time option, where:
ps -options arg1 arg2
(with no '-' on "arg1" and "arg2") was treated as:
ps -options -N arg1 -M arg2
This also changes `ps' to check for any additional arguments after
processing all the '-'-options, and attempt to use those arguments as
a pid or pidlist. If an extra argument is not a valid pidlist, then
`ps' will print an error and exit. This seems a more generally useful
extension of the kludge-option processing than the -N/-M behavior, and
has fewer confusing side-effects.

those options are implemented in src/sys/kern/kern_proc.c (v1.203).

This is an often-requested feature.
Use wcwidth() to determine the number of column positions a character
takes up, although there are still a few places left where we assume
1 byte = 1 column position, e.g. line-wrapping when handling the -m option.
The error handling here is somewhat more complicated than usual: we do
our best to show what we can of a filename in the presence of conversion
errors, instead of simply aborting.

This corrects a problem of lost-precision for `-r' (sort-by-CPU). Also,
for sort-by-CPU and sort-by-memory, any processes which have the same
value CPU or MEMORY are now sorted by TTY and then (if needed) by pid.
