- Removed dead declarations
- Made objects that should have been declared as static, static.
The changes use STATIC instead of static, following the existing
convention in the rest of the code.

- 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
Sync with HEAD, except that printf(1) is still a shell builtin and old2002-07-19T04:38:54ZTim J. Robbinstjr@FreeBSD.org2002-07-19T04:38:54Zurn:sha1:b6479dc1641d2ef3c9a958e806b3be23e8bfb984
libedit history interface is still used. This gives the following
new features/bug fixes:
- Quote output of alias, export, readonly builtins
- -L (logical) and -P (physical) options added to cd and pwd, logical
behaviour made default.
- -C (noclobber) option and >>| redirection is implemented
- hash builtin only shows normal commands, no functions or builtins
- -u (nounset) option is implemented
- fc builtin's -e option works correctly again
- No longer assumes there is a tty on fd 2 (PR 36671)
- fg/bg command show more info about job being manipulated
- -l and -s options added to jobs builtin, output closer to POSIX spec.
- %+ (current job) %- (previous job) and %? (substring) job ID's implemented
- >&- (and similar) redirection operators close descriptors correctly
- set +o output corrected
- Style: __FBSDID, __P removal, ANSI-style function declarations
