Update the documentation to reflect this. Thanks for catching this. Patch looks good. There is another section later in the documentation which details the various exit codes and what they mean. But it seems to have never actually documented this case, so we don't need to update it. :) -Peff ^ permalink raw reply [flat|nested] 7+ messages in thread

I wondered if we should explain the significance of "last" a bit more (like "this results in the value from the most specific configuration file to be used, the ones in $GIT_DIR/config overriding what is in $HOME/.gitconfig"), but I do not have a strong opinion either way.

If you read carefully, I think it is implied by the "files are read in order given above", but it took me a minute to think about it. Maybe add at the end: ...values of a key from all files will be shown, in the order the files are processed (least specific to most specific). Or something (I do not like "least specific" because we have not introduced that term earlier, but I can't think of another succinct way to say it). But even without that, the patch is certainly an improvement. -Peff ^ permalink raw reply [flat|nested] 7+ messages in thread
