df9e587beb There is a built-in command called "builtin"; spell its name correctly 
after rev. 1.77 called it "built-in".

8eed22b1a6 Fix a few typos, among them s/builtin/built-in/ (except for the ref 
to the builtin(1) man page.) This is for consistency with the spelling
both proposed by ispell as well as IEEE Std 1003.1-2001.

4f8fa749f0 Avoid accessing the current job's process table in the child part of 
forkshell() after it has been freed. This caused mysterious behaviour
when anything but the first command in a pipeline tried to access the
terminal when the `junk' malloc() option was enabled (which is the default).

7e1975c2b2 Add a -P/-o physical option which behaves similarly to bash/ksh's options 
by the same name. This option makes the cd and pwd builtins behave physically
(as opposed to logically) by default.

be58cc483e Avoid calling el_resize() from a signal handler, even though libedit 
itself does that if you set EL_SIGNAL. Instead, set a flag and check it
before calling el_gets(). This is safer, but slower to respond to changes.

2babaf74b5 Implement the P1003.2 `command' builtin command, which is used to suppress 
shell function and alias lookup. The -p option has been implemented, the
UPE -v and -V options have not. The old `command' command has been renamed
to `builtin'.

b80be28218 Avoid using ints or shorts to store process id's, use pid_t instead. 
The pgrp member of struct job was declared as a short and could not store
every possible process group ID value, the rest of them were benign because
pid_t happens to be an int.

6c8bbe749e Don't assume the shell's controlling terminal is attached to file descriptor

many other parts of the shell are no longer compatible with this, and it
