The problem is scripts/headers_install.pl
Here we do:
$line =~ s/([\s(])__user\s/$1/g;
And this zaps the newline when we see __user.
It is not obvious why this zaps the newline - must be
some perl foo I have forgotten.
I checked this by removing the unlink in said perl script
and looking at the .tmp file.
