There several tests in t1300-config.sh that validate failing invocations
of "git config". However, there are no tests that check what happens
when "git config" is asked to retrieve a value for a missing key.
Add tests that check this for various combinations of "<section>.<key>".
---
The patch is marked as RFC, because I'm not sure if such a test is useful or
not. Even if it is not useful as a test, maybe it would be useful as
documentation of behavior for people reading "t1300-config.sh"?
Having multiple tests for different kinds of keys might also be overkill, and
just one test for a single key is enough. Conversely, there aren't enough
tests -- tests for keys with subsections are missing.
