c848bc18e8 sh: Improve the command builtin: 
* avoid unnecessary fork
* allow executing builtins via command
* executing a special builtin via command removes its special properties

29d401c22d sh: Do not run callers' exception handlers in subshells. 
Reset the exception handler in the child to main's.

This avoids inappropriate double cleanups or shell duplication when the
exception is caught, such as 'fc' and future 'command eval' and 'command .'.

772e9b41df Disable job control when running 'sh -i' in the testsuite. 
Job control tty manipulations sometimes cause the tests to stop (SIGTTOU
and the like) when run from the 'prove' tool.

eaa3489312 sh: Ensure the same command input file is on top after executing a builtin. 
This avoids weirdness when 'fc -e vi' or the like is done and there is a
syntax error in the file. Formerly an interactive shell tried to execute
stuff after the syntax error and exited.

This should also avoid similar issues with 'command eval' and 'command .'
when 'command' is implemented properly as in NetBSD sh.

Special builtins did not have this problem since errors in them cause the
shell to exit or to reset various state such as the current command input
file.

e3c2cd7237 trap: do not consider a bad signal name a fatal error. 
POSIX explicitly prescribes this.
Continue processing any other signals and return status 1.

Also document various properties of special builtins that we implement.

I'll commit real soon.
