Yup (I locally did something similar when queued it).

Good suggestion.

Existing `color.branch` is already loose in the same way, but others
like color.{diff,grep,interactive} read better. No, past mistakes
by others is not a good excuse to make things worse, but I'd say it
also is OK to clean this up, together with `color.branch`, after this
change on top.

Hmm, do we actually say things like "Error: blah"? I am not sure if
I like this strncasecmp all that much.

Sounds good.
I didn't comment on other parts of your review posed as questions
(that require some digging and thinking), but I think they are all
worthwhile thing to think about.
Thanks.
