It is somewhat disturbing to see that this only takes effect when
cmit_fmt_is_mail(pp->fmt) and completely ignored otherwise.  Seeing
pp->fmt and pp->name_and_address_only sitting next to each other, it
looks like a layering error.

I wonder if you instead want a new value for pp->fmt that
cmit_fmt_is_mail() considers an e-mail format but is different from
what we used for usual e-mail format?

This error handling is also disturbing.  What makes it correct to
parrot the original input that does not parse correctly as an ident
line to the output, only when name_and_address_only bit is on?  It
does not make any sense to do so when cmit_fmt_is_mail(pp->fmt) is
false, especially.
