MFC:
- Avoid duplicate error messages when invalid options are used with the
  cd, pwd, fc, and export builtins.
- Handle window size changes when line editing is enabled.
- Don't access memory after it is free()'d, fixing strange job control
  problems when the J (junk) malloc() option was enabled.
- Read libedit options from ~/.editrc if present.
- Change the `command' builtin to be what POSIX.2 requires, create a
  `builtin' command to execute builtin commands.
- Add a `bind' builtin command to modify key bindings.
- Store process ID's in pid_t's instead of short's.
- Removed unused #ifdef'd code.
- -P (-o physical) option to make -P the default for the cd and pwd builtins
