commit c3cc85a3c5ab8491266b207eeb1fb6b6061274ed
from: Stefan Sperling <stsp@stsp.name>
date: Tue Apr 30 13:36:58 2024 UTC

make gotd notifications work when 'git push' is used instead of 'got send'

Git clients disconnect earlier, which resulted in session_write exiting before
notifications were sent. Do not treat early EOF as a fatal error if we are
sending notifications. Add regression test coverage for 'git push'.

Problem found by Thomas Adam.
