[RFC] send-email quote issues

Matthieu Moy [off-list ref] writes

I would say that using parse_address_line is good for consistancy in Git 
anyway. If the behavior of parse_address_line is broken on some 
corner-cases, then it should be fixed anyway. 

Ok, but I don't know what fixed means in these particular cases.
Actually the problem when we have a quote in a name is: Is this a
delimiter or is this an ascii char?

Currently the problem is solved by saying : it's an ascii char
unless there is two quotes aroung all the name (modulo minor
things). So if I write:

--to='"Jane, Kararina" Doe [off-list ref]'

they are considered characters. Which means that this is
different than:

--to='"Jane, Kararina Doe" [off-list ref]'

Is this expected?
