9c6ea7014e 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.

8be25d316f Catch SIGWINCH in interactive shells and call el_resize() to update

f9fd5faa32 Add a `bind' builtin command, which is simply a wrapper around libedit's 
builtin command of the same name. This allows the key bindings for the
shell's line editor to be changed.

bd9024b4d7 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'.

9e3506ab60 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.
