OK, so you are getting rid of distinctions between sanitized_sender
and sender, and $sender is now defined to be always "sanitized"
form.
That change makes things consistent with respect to the question I
had on [2/6].
I however wondered how this would affect those who have configured
"sendemail.from" with an already "sanitized" address. That is, you
may have used:
[sendemail]
from = "Michael S. Tsirkin" <[email protected]>
with the older and current versions of Git. I _think_ the safetly
of this change relies on that it is a no-op to run sanitize_address
on an already sanitized address (i.e. feeding the above example
sendemail.from to sanitize_address gives back the same string),
which holds true for all practical purposes, but it is a bit subtle.
