Does this work at all? On my machine $size(4) is `mjd', because there's
a double space between the permissions and the link count except when
the number of links exceeds 9.
-rw------- 1 mjd 0 Jun 28 16:24 /var/spool/mail/mjd
In fact, it's very difficult to get the size, because it's $size(17),
unless the size exceeds 9 bytes, in which case it's $size(16), unless
the size exceeds 99 bytes, inwhich case it's $size(15)...
Who was it who said that the $ifs behavior was doing the right thing?
