[Pbuilder-maint] Bug#363916: pbuilder exits and cleans build directories even with --save-after-login when exit code is 1.

[Junichi Uekawa]

Package: pbuilder
Version: 0.151

Probably the following code should check for SAVE_AFTER_LOGIN
function cleanbuildplace () {
    if [ "$?" -ne 0 ]; then
	echo " -> Aborting with an error";
    fi
    if [ "${INTERNAL_BUILD_UML}" != "yes" ]; then
	if [ -d "$BUILDPLACE" ]; then 
	    echo " -> cleaning the build env "
	    clean_subdirectories "$BUILDPLACE"
	fi;
    fi
}



otherwise, exit 1 from pbuilder login prompt will result in cleaning
