d8654c644a Use statfs instead of getmntinfo(). This will make the procfs checks
play nicer in prisons. It also simplifies things.

a951d1f83b Currently if the user specifies -e and procfs is not mounted on /proc,
printing of the process environment will fail silently.

-define a function which will check to see if procfs is mounted on /proc
-Implement this test if the user specified -e
-If procfs is not mounted on /proc and -e was specified, print a warning.
 informing the user that procfs(5) is required.

f2fbfae6b0 Improve checking for `ps -t <dev>', and give better error messages when
an invalid <dev> is specified.  Aside:  It turns out that the S_ISCHR()
check is true for almost every device that we have (not just tty's).

e4b70e6697 When displaying the "COMMAND" field for system-processes and/or kernel
threads, put the command name in square brackets instead of parenthesis.
This matches NetBSD, and also seems to be what linux does.  The sentence
which is added to the man page is taken straight from NetBSD.

ce1affa2ac From SUSv3:
Any [standard output] field need not be meaningful in all
    implementations. In such a case a hyphen ('-') should be
    output in place of the field value

So have the `-O label' option print out the string "  -" if the
process has no label.

4bac4483db Have the main() routine calculate %CPU and (if needed) memory information
when copying per-process info before starting to sort the list.  This way,
sort-by-CPU or sort-by-memory will only calculate values once-per-process,
instead of twice-per-comparison.  Also take advantage of this to simplify
the pscomp() routine.

de1702f459 Fix so `ps' catches and complains about null-values specified for a
process id, instead of using pid==0.  Ie, `ps -p 12,' and `ps -p ,12'
are now errors (instead of being treated like `ps -p 0 -p 12').

bf46a3bf10 Additional tiny adjustment to kludge-option processing so `ps t p0'
is treated like `ps -t p0', instead of changing it to `ps -T p0'.
Note that `ps t' is still changed to `ps -T', since that is one of
the main reasons for this kludge processing...

c675340a5c Rewrite the kludge-option processing to improve how it handles a few
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.
