Also, my reading was incorrect as "local part" refers to the text preceeding
the @ character, not the text outside the <>. So, while the name should probably
be quoted to avoid problems with MUAs interpretting the , as a list separator, I
don't have anything definitive to reference to prevent it. So at least for now,
I'll be accepting Lad's contributions as is, comma and all :-)

I really dislike this aspect of our tooling. Being so free form, it's
inevitiable for even seasoned contributors to trip over these sort of implicit
rules. It seems to me that a very significant, perhaps not the majority, of the
time I spend as maintainer is dealing with things like coding style, commit
message formatting, and similar issues. I can sympathize with those who
criticize our mechanisms as archaic :-/
