el_gets now sets el_len to -1 on error so we can distinguish
...
between a NULL string and an error.
This fixes sh from exiting with libedit now allowing EINTR to return.
We may need to expand this to an errno check in the future.

Don't close any script files if vfork is set.
...
If a fork() is done later in order to feed a 'here' document into a pipe
then it is possible that one end of the pipe might get closed.

Fixes from David Laight:
...
- ansification
- format of output of jobs command (etc)
- job identiers %+, %- etc
- $? and $(...)
- correct quoting of output of set, export -p and readonly -p
- differentiation between nornal and 'posix special' builtins
- correct behaviour (posix) for errors on builtins and special builtins
- builtin printf and kill
- set -o debug (if compiled with DEBUG)
- cd src obj (as ksh - too useful to do without)
- unset -e name, remove non-readonly variable from export list.
(so I could unset -e PS1 before running the test shell...)

VFork()ing shell: From elric@netbsd.org:
...
Plus my changes:
- walking process group fix in foregrounding a job.
- reset of process group in parent shell if interrupted before the wait.
- move INTON lower in the dowait so that the job structure is
consistent.
- error check all setpgid(), tcsetpgrp() calls.
- eliminate unneeded strpgid() call.
- check that we don't belong in the process group before we try to
set it.
