Are you proposing an alternative/better fix here? or describing what
this patch does?

My tree doesn't have in it d67738db but from the example you give above
it seems like this patch will regress that? As someone who already gets
too much mail and is listed in THE REST these days I am very much in
favour of not mailing THE REST when other maintainers have been found.

That's fine IMHO. The script shouldn't be expected to be smart enough to
reconcile two distinct strings which happen to refer to the same person
into a single string. If someone cares they should patch MAINTAINERS to
refer to themselves in a consistent way.
