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.

My earlier attempt to fix this (v1.65) only seemed to work because of a
lucky random value in nentries (which was not being initialized back
when I tested that earlier patch).
is compiled with LAZY_PS, so that there is only one PS_ARGS string to
modify when changing the option-list. Also get `-f' to show up in the
usage() statement when compiled with LAZY_PS.
- Change `-p' to allow a list of process IDs, and `-t' to allow a list
of terminal names, instead of only a single value for each.
- Add the `-A' option of SUSv3, which is exactly the same as `-ax'.
- Add the `-G gidlist' (group id).
- Allow any of these "selector options" to be specified multiple times,
and have `ps' keep adding to a given list -- instead of replacing the
previously-specified values.
- Fix interactions between selector-options, so that: "If any are
specified, ... ps shall select the processes represented by the
inclusive OR of all the selection-criteria options." (from SUSv3)
- Add a `-X' option, which is the reverse of the `-x' option.
- various minor improvements in parsing and error handling.
This does not get us to match POSIX/SUSv3, but it gets us closer. The
`-g pgidlist', `-R ruserlist' and `-s sidlist' options mentioned in
freebsd-standards are still under debate, so they skipped for now.
It should be true that this introduces no user-visible incompatible
changes, except to support "new stuff" that was not supported before.

- Document the correct default when no -N is specified.
- Remove stale reference to /var/db/kvm_kernel.db.
- Remove stale reference to /var/run/dev.db.

Also adds support for <x> being a comma-separated list of processes, and does
a much better checking for invalid-values of <x>, such as 'ps -p someword'.

that this provokes. "Wherever possible" means "In the kernel OR NOT
C++" (implying C).
There are places where (void *) pointers are not valid, such as for
function pointers, but in the special case of (void *)0, agreement
settles on it being OK.
Most of the fixes were NULL where an integer zero was needed; many
of the fixes were NULL where ascii <nul> ('\0') was needed, and a
few were just "other".

in the comment applies to a decision that needs to be made in relation
to the year 2000.
In fact, that statement probably should be changed to be
more generic (getting the year from the current time perhaps). Otherwise,
starting in 2069 two digit year conversions in date(1) will start assuming
1900 instead of 2000. hehe.
1. Sizes in the range 1000 -- 1023 units require four characters width
for the integer; increase the field width to accomodate this.
2. Sizes in the range 9.95 -- 10 units were being displayed as "10.0"
units; adjust the logic to fix this, and now that we've got an extra
character of field width, print fractional units if the size is less
than 99.95 units.
3. Don't display sub-byte precision.
This should mean that the following sizes are displayed:
0B .. 1023B
1.0U .. 9.9U
10.0U .. 99.9U
100U .. 1023U
for values of U in "KMGTPE".

Only use return value from system call if system call succeeded.
Tested with `make world` and some of my own scripts.
This should be MFCed soon. While /bin/sh is hard to test the fix is
obviously correct and can be assumed not to break something else
(famous last words...).
