OK, I had a look and made a patch to fix this as well. Please see v3
which is on its way to your inbox.
Regarding the .dts* patch, I need some feedback below before sending
anything, so I did not include it in the series.

Hmm, I ran this over the arch/ directory on all .dts* files and got some
false positives:
1355276466-18295-1-git-send-email-arve@...roid.com
This one comes from a lore link with a Message-ID. So deleting URLs
before parsing should fix it.

These can also be avoided by strengthening the email parsing regex
to more strictly validate the TLD, which may not begin with a digit.
So something like this:
diff --git a/scripts/get_maintainer.pl b/scripts/get_maintainer.pl
index faa96801897a..e253053da967 100755

Given that some changes are needed, I want your input on how to send:
1. Should I send the above diff as a patch preceding Shawn's patch?
2. Should I send the above diff as a patch following Shawn's patch? Here
the justification is arguably more clear in the history.
3. Or should I roll it into Shawn's patch? If so, Shawn, may I have your
Signed-off-by?
Kind regards,
Alvin
