A use reported a submodule issue regarding strange case indentation issues, but it could be boiled down to the following test case: $ git init test && cd test $ git config foo."Bar".key test $ git config foo."bar".key test $ tail -n 3 .git/config [foo "Bar"] key = test key = test Sub sections are case sensitive and we have a test for correctly reading them. However we do not have a test for writing out config correctly with case sensitive subsection names, which is why this went unnoticed in 6ae996f2acf (git_config_set: make use of the config parser's event stream, 2018-04-09) Make the subsection case sensitive and provide a test for writing. The test for reading is just above this test.
