Modified Files:
        src/bin/sh: exec.c

Log Message:
DEBUG changes: convert DEBUG TRACE() calls to new format.
ALso, cause exec failures to always cause the shell to exit with
status 126 or 127, whatever the cause.  127 is intended for lookup
failures (and is used that way), 126 is used for anything else that
goes wrong (as in several other shells.)  We no longer use 2 (more easily
confused with an exit status of the command exec'd) for shell exec failures.
