Right, but I have no way to immediately see which patches I have been
Cc-ed on. Unlike you (iiuc) I'm subscribed to the list, and hence mails
all look the same whether or not I'm CC-ed. Then again I only now
realize that there are ways to filter what I've got - I'm sorry for
not having thought of this earlier.

For a large series mostly touching Arm code, calling out the
"outliers" (when patch titles don't make this clear) could certainly
help. It's not like I'm asking to do such everywhere.
