$ fatal: bad config file line <nn> in <config>
The same with quoted:
[someSection]
qthisKey = "has\na\nvalue\with\nseveral\nnewlines"
There is no escaping besides escaping " and escape character
i.e. escaping \ in git config. Se "\n" would work as well as NUL.
(It is said explicitely that subsection names cannot contain "\n").

But only for "git repo-config --bool --get section.noval" output.
Semantically equivalent to "true".
But without --bool it returns like it was "".
