Commit 3709a386 ported hooks codes to new command execution API,
together with the useful error message removed. Though we can't
get "errbuf" from the new command execution API anymore, still
we can give a more useful error.

Needs to be: if (ret == 0 && exitstatus != 0).
If ret is -1 (possible if the command completely failed, such as if
you are OOM or the child died due to a signal rather than a normal
exit), then exitstatus might be undefined.
Make sense, and I pushed with the addition, Thanks
