bdf0a24b3d Don't remove the destination file if there is a write error. This is 
very bad if it is actually a device or fifo.  POSIX.2 requires that a
diagnostic message be written, the file descriptor be closed, and for
cp to continue on with the rest of the files.

23e6aab105 Use "utility" instead of "command". Modern definitions of these terms 
are distinct (See POSIX.2 glossary).

A utility is a executable, script or shell builtin; while a command
can be any of those things plus lists, pipelines, compound commands
(if, for, while) and shell function definitions.

782cb68126 Fix bin/1240, from Dennis Ferguson. the exit builtin with no arguments 
should return the exitcode of the previous command but it always returned 0.

88fc62fe16 Changed type of rlimit values from quad_t to rlim_t. Cast rlim_t's to 
quad_t's and use "%qd" in printf.

9d255ec409 Ignore result of sigaction when setting traps. Traps will succeed even 
on SIGKILL or SIGSTOP. This is what other bourne shells do. (suggested
by mycroft)

b842cc2784 Avoid trapping SIGKILL. Pretend that we did, so that we will not keep 
failing trying to trap it later. This is what the other bourne shells do.

$ FOO=1 . ./foo

are honored during and after the execution of the script.

4fb6f609aa Changed so that syntax errors (EXERROR) set the exit status to 2, 
and commands that are not found set the exit status to 1 like all
other bourne shells.

fbac2e9de2 Fixed new bug the previous fix introduced: 
false
    foo=bar
    echo $?

would print 1
Also fixed the long standing bug:

    false
    echo `echo $?`

would print 0
The exitstatus needs rethinking and rewriting. The trial and error method
is not very efficient
