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.

was worried about truncation of arg_max by this cast, but if it gets truncated,
we know it'll obviously be greater than SIZE_MAX anyway.

function seems to do the right thing, and is not a "stub", and whoever "marc"

him any longer.
correct manner. Revert my incorrect change to use err(3) for malloc(3)
failing. Use a size_t variable to store the size of the argument buffer
we allocate, and remove silly casts as the result of having this around.
Modify the math in some of the paranoid checks for buffer overflow to
account for the fact we now are dealing with the actual size of the
buffer. Remove the static qualifier for arg_max, and the bogus setting
of it to -1.
Include <limits.h> for the definitions we use to check for possible
overflows.

o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
You can get ps easily to core dump, if you are running a "make depend"
on a kernel in one window and a "ps -auxww" in another. The ww will
try to give you the full argument list of the command that can
now be 64Kb large, but ps expected only 4Kb large arg arrays and
doesn't check for overflows.
