misleading error message stating that args[0] did not exist when

did not exist.
It now keeps track of if the child got as far as preexec and reports it if
not back to the parent via a special "noexec" error message value in
the error pipe so that the cwd can be blamed for a failed chdir
instead of the exec of the executable being blamed instead.
The executable is also always reported accurately when exec fails.
