emsource does not return return code from dpkg-buildpackage

[David Goodenough <david.goodenough@btconnect.com>]

If dpkg-buildpackage fails, emsource stops but does not return a non-zero 
return code.  Now I suppose it might be that dpkg-buildpackage does not
return a non-zero return code, but I am not sufficiently familiar with 
it to know.

Does anyone know what is supposed to happen?
