Hi!

This one's weird, since I've written dozens of this sort of table before
and it's always worked, but this is somehow broken. A minimal example is
-- >8 --
=2ESh NAME
=2ENm a
=2E
=2ESh EXAMPLES
=2EBd -literal
=2ENm
b
=2EEd
-- >8 --

Which yields
-- >8 --
nabijaczleweli@tarta:~/uwu/mandoc$ ./mandoc -mdoc -Thtml -Ofragment ../kl.8
<table class=3D"head">
  <tr>
    <td class=3D"head-ltitle">UNTITLED</td>
    <td class=3D"head-vol">LOCAL</td>
    <td class=3D"head-rtitle">UNTITLED</td>
  </tr>
</table>
<div class=3D"manual-text">
<section class=3D"Sh">
<h1 class=3D"Sh" id=3D"NAME"><a class=3D"permalink" href=3D"#NAME">NAME</a>=
</h1>
<p class=3D"Pp"><code class=3D"Nm">a</code></p>
</section>
<section class=3D"Sh">
<h1 class=3D"Sh" id=3D"EXAMPLES"><a class=3D"permalink" href=3D"#EXAMPLES">=
EXAMPLES</a></h1>
<div class=3D"Bd Li">
<pre><code class=3D"Nm"></code></pre>
a
b</div>
</section>
</div>
<table class=3D"foot">
  <tr>
    <td class=3D"foot-date"></td>
    <td class=3D"foot-os"></td>
  </tr>
</table>
-- >8 --

Note how a and b are both (a) past Nm and (b) past the <pre>. This has
an additional funny side-effect of inlining the rest of the display
block. Macros still work, but text is laid normally by the browser,
rather than literally.

I don't know what triggers this in this case and not all others,
but an explicit .Nm argument fixes it (but that's, uh, suboptimal).

Happens on mandoc 1.14.5-1 off Debian and 2021-10-12T21:41:37+02:00 off
CVS.

Best,
=D0=BD=D0=B0=D0=B1
