SubjectRe: [PATCH v2] coccinelle: strncpy+truncation by strscpy

I've seen both being done (if you look at the git log of the linux
kernel and search for 'v2' you will have some matches)

The list was a bit long in this case, but I think it's worth at least
mentioning that the previous version used strlcpy and why I changed in
the commit message.

Eh, I must have been really unlucky with the scripts I looked at, one
just happened to have SUGGESTION used like this (misc/warn.cocci), but
now you said that I can see it's the only one!

I'm not sure on what to do here, if you think there could be scripts
relying on that then I'll change this to WARNING, but the wording feels
a bit strong and "suggestion" leaves more room for interpretation.

Replying here instead to limit the number of mails sent,
I think people would look at git blame/log if there is no name in the
file, but I can understand it is simpler if a name is present.

Just a nitpick on format, all copyright comments on cocci scripts end
with the license; since that will be added as an SPDX tag instead do you
mind if I do not list it again there?

Also just a head's up, I'll be AFK for the next ~48 hours; I'll post a
v3 of the patch with license/copyright added, possibly suggestion
changed, and whatever else comes up by then :)
