<p><var>repeat</var>, <var>size</var> and <var>value</var> are absolute expressions.
This emits <var>repeat</var> copies of <var>size</var> bytes.  <var>Repeat</var>
may be zero or more.  <var>Size</var> may be zero or more, but if it is
more than 8, then it is deemed to have the value 8, compatible with
other people&rsquo;s assemblers.  The contents of each <var>repeat</var> bytes
is taken from an 8-byte number.  The highest order 4 bytes are
zero.  The lowest order 4 bytes are <var>value</var> rendered in the
byte-order of an integer on the computer <code>as</code> is assembling for.
Each <var>size</var> bytes in a repetition is taken from the lowest order
<var>size</var> bytes of this number.  Again, this bizarre behavior is
compatible with other people&rsquo;s assemblers.
</p>
<p><var>size</var> and <var>value</var> are optional.
If the second comma and <var>value</var> are absent, <var>value</var> is
assumed zero.  If the first comma and following tokens are absent,
<var>size</var> is assumed to be 1.
