add proper exit status for scripts

[DerDakon]

ideally I would like to do something like

./foo-useflags.sh  && ./foo-rdeps.sh && ./foo-commit.sh

To make this work the return value needs to be accumulated across the script steps and only returned at the end.

Random drive-by comment, was just browsing through the issues :)
If I understand the question correctly you can achieve this using pipefail, see https://www.gnu.org/software/bash/manual/html_node/Pipelines.html
