When a child is receiving SIGSTOP, eval continues with the next
command. While that is correct for the interactive case (Control-Z
and you get the prompt back), it is wrong for a shellscript, which
just continues with the next command, never again waiting for the
stopped child. Noted when childs from cronjobs were stopped, just to
make more processes (by wosch).
The fix is not to return from a job wait when the wait returned for a
stopped child while in non-interactive mode. This bahaviour seems to
be what bash2 and ksh implement. I tested for correct behaviour for
finnaly killing the child with and without forgrounding it first.
When not foregrouding before killing, the shell continues with the
script, which is what the other shells do as well.

This makes "mkdir /nonexistant/foo" complain that /nonexistant
doesn't exist rather than /nonexistant/foo which doesn't make much
sense.

no longer contains kernel specific data structures, but rather
only scalar values and structures that are already part of the
kernel/user interface, specifically rusage and rtprio. It no
longer contains proc, session, pcred, ucred, procsig, vmspace,
pstats, mtx, sigiolst, klist, callout, pasleep, or mdproc. If
any of these changed in size, ps, w, fstat, gcore, systat, and
top would all stop working. The new structure has over 200 bytes
of unassigned space for future values to be added, yet is nearly
100 bytes smaller per entry than the structure that it replaced.
This lets you resolve pathnames to their underlying physical path:
critter# realpath /sys/kern/subr_disk.c
/freebsd/src/sys/kern/subr_disk.c
Update the pwd man-page slightly.
- The ability to specify elements by volume tag instead of their actual
physical location. e.g., instead of:
chio move slot 3 slot 4
you would now use:
chio move voltag FOO slot 4
- The ability to return an element to its previous location, as specified
by the source element. e.g., instead of:
chio move drive 0 slot 4
you would now use:
chio return drive 0
or
chio return voltag FOO
These features will obviously only work with changers that support volume
tags and/or source element IDs. chio(1) should fail gracefully if the user
attempts to use these new features and the source element ID or volume tag
are not found.

Problem in this code originally spotted by
Jun Kuriyama <kuriyama@FreeBSD.org>
growstackblock() sometimes relocates a stack_block considered empty
without properly relocating stack marks referencing that block.
The first call to popstackmark() with the unrelocated stack mark
as argument then causes sh to abort.
Relocating the relevant stack marks seems to solve this problem.
The patch changes the semantics of popstackmark() somewhat. It can
only be called once after a call to setstackmark(), thus cmdloop() in
main.c needs an extra call to setstackmark().

flag has been depricated, although it still works with a warning
message, and replaced with an environment variable CLICOLOR (command
line interface colour). This could be used by other tools that
want to be able to control colour output.
In addition if the environment variable CLICOLOR_FORCE is defined
colour sequences are output irrespective of whether the output is
directed to a terminal (as long as TERM references a colour capable
terminal of course ;)
