Hmph. That's a merge.
Merge branch 'rs/c-auto-resets-attributes'
When "%C(auto)" appears at the very beginning of the pretty format
string, it did not need to issue the reset sequence, but it did.
* rs/c-auto-resets-attributes:
pretty: avoid adding reset for %C(auto) if output is empty
And neither of the two colon containing line remotely resembles how
a typical RFC-822 header is formatted. So that may serve as a hint
to how we can tighten it without introducing false negative.

Yes.
These are exactly why I mentioned "if certian number or percentage"
in my earlier suggestion.
I think in practice, "A paragraph with at least one Signed-off-by:
line, and has no more than 3/4 of the (logical) lines that do not
resemble how a typical RFC-822 header is formatted" or something
along that line would give us a reasonable safety.
Your Java example will fail the criteria in two ways, so we'd be
safe ;-)
