It may be a good convention to have LF at the beginning of a new
string (i.e. we terminate the old line only when we have something
more to say), but that is true only when we want to end the sentence
without the final newline.  I wonder if that is true in this case;
do we want perl to say "at line # in file X" at the end?

In any case, you have two output lines that ends with a trailing SP
just before LF, which is probably not what you wanted.

If we want to see all lines end with LF, it may be far easier to
read this way:

	die "msg\n",
            "\tvar1=val1\n",
            "\tvar2=val2\n",
            defined $var3 ? "\tvar3=val3\n" : "";

I dunno.
