9fa1d120a0 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.

9da5e43f4d Since interpreting ELF binaries as shell scripts is not very useful, and 
since the current error message is less than helpful, improve it.

a9fc176e82 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.

c02b3bbdf4 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...)

edcb454443 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.

893ade3fac - fix PR1620, -DNO_HISTORY did not work. 
- restore parsing state after parsing old style command substitution.
  The ';' in '`echo z;`' broke the following:
	for i in 1; do
		cat > /dev/tty << __EOF__
		`echo z;`
		__EOF__
	done

cVS: Enter Log.  Lines beginning with `CVS: ' are removed automatically

c1b02d9bff - Fix -v flag, so that it works properly when the shell reads from scripts.
