1c753c98f9 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).

8714fd098c Don't continue if the '-C' option (a-la GNUtar; commited in options.c
rev 1.18, but not documented in the man page) caused a failed chdir.
Otherwise, one can easily overwrite files.

09466dade0 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.

26d7dd0b9a 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.

4586528554 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.

89c138dcf0 If we are asked to print the total number of blocks, do so even if we
have no entries to print (either due to an empty directory or an
error).  This makes the -l and -s options more consistent, like
Solaris and (Debian) Linux.  To make this happen, tweak two
optimizations on the second call to display():

- Don't skip display() altogether, even if list == NULL.
- Don't skip the call to the printfn in display() if we
  need to print the total.

08c3b6bf16 Convert fsbtoblk() from a macro to a function. The redundant
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.

7a915f30a7 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...

3672d683c6 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.
