I'm not talking about the formating, but about die's handling of
$!.  Die is clearly designed to be called immediately after an
error from a function which updated $!.  Any other attempt to
use die _must_ be protected with `$! = 0;', or `die' might reuse
an obsolete $! value from a former error (it's even worse: I
think the recent WEXITSTATUS issue was caused by Perl's
autoloading of WEXITSTATUS failing to preserve $!).
