- 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

Got two volatile sig_atomic_t and int mixed up.

i.e. this makes emacs usable from system(3). Programs called from
shellscripts are now required to exit with proper signal status. That
means, they have to kill themself. Exiting with faked numerical exit
code is not sufficient.
Exit with proper signal status if script exits on signal.
Make the wait builtin interruptable, both with and without traps set.
Use volatile sig_atomic_t where (and only where) appropriate.
(Almost) fix printing of newlines on SIGINT.
Make traps setable from trap handlers. This is needed for shellscripts
that catch SIGINT for cleanup work but intend to exit on it, hance
have to kill themself from a trap handler. I.e. mkdep.
While I'm at it, make it -Wall clean. -Wall is not enabled in
Makefile, since vararg warnx() macro calls in usr.bin/printf/printf.c
are not -Wall-able.
