[BUILTIN] Use EXEXIT in place of EXEXEC
The intended semantics of EXEXEC are identical to EXEXIT, so simplify by using EXEXIT directly. Functional change: in edge cases (exec within a trap handler), this causes the exit status from exec not to be clobbered. For example, without this patch: $ sh -c 'trap "exec nonexistent" EXIT'; echo $? exec: 1: nonexistent: not found 0 And with it: $ sh -c 'trap "exec nonexistent" EXIT'; echo $? exec: 1: nonexistent: not found 127 Signed-off-by: Jonathan Nieder <jrnieder@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
