[U-Boot] [PATCH] patman: separate emails in CC list with NULs

[Dmitry Torokhov <dmitry.torokhov@gmail.com>]

There is a contributor in Linux kernel with a comma in their name, which
confuses patman and results in invalid to- or cc- addresses on some
patches. To avoid this, let's use \0 as a separator when generating cc
file.
