That is because this option relates to the input given. Other options relate to the items to be processed, such as grep.color.* which I would not find strange if they were respected in the submodule.

In an ideal world we should pay partial attention to the config in the submodule, and for each config key we'd have to determine if it rather relates to the general runtime (grep.threads), the command line options (grep.patternType) or to the specific content inside the repo (coloring, whether we show the line number).

For now and in reality we can ignore the content specific settings and claim that any setting here is related to runtime and command line options, both of which a user may expect the superproject to win in case of differing configurations.

Thanks, Stefan
