Is there an EASY way to make 'git format-patch --cover-letter $commitid' 
(and git send-email, by extension) automatically search for all cc's any 
any of the N/M patches, and auto-cc ALL of those recipients on the 0/N 
cover letter?  And if that is not something easily built into git 
format-patch directly, is it something that can easily be added to 
sendemail.cccmd?  This is not the first time that someone has complained 
that automatic cc's are not sending the cover letter context to a 
particular maintainer interested (and auto-cc'd) in only a subset of an 
overall series.

On the other hand, cc'ing all recipients for a largely mechanical patch 
series that was split into 67 parts, in part because it touches so many 
different maintainers' areas, may make the cover letter have so many 
recipients that various mail gateways start rejecting it as potential spam.
