Yeah, I agree it needs to be the main justification in the commit message. I do wonder, though, if we're digging ourselves a hole with the inconsistency between different --types that will bite us later. Given that it's not that hard to chomp the output (and as you noted, the shell does it fairly transparently), and given that the caller has to switch between "--get-color" and "--type=color", it's not that hard to handle the output differently if you know to do so. Mostly I was just surprised by the new behavior. Perhaps the right solution is not a patch to the code, but to the documentation. Something like: diff --git a/Documentation/git-config.txt b/Documentation/git-config.txt index 495bb57416..61f3a9cdd7 100644 --- a/Documentation/git-config.txt +++ b/Documentation/git-config.txt @@ -252,7 +252,9 @@ Valid `<type>`'s include: output.
