Thank you Ingo!

Anyway, in my firefox,
http://man.openbsd.org/OpenBSD-current/man5/ssh_config.5
displays the synopsis as

SYNOPSIS
  ~/.ssh
  /config 	

  /etc/ssh
  /ssh_config 	


Only after I make the font smaller than 100% (with Crtrl + -) it becomes

SYNOPSIS
  ~/.ssh/config 	
  /etc/ssh/ssh_config

Why is that? Could it be besause of the hardwired width?
(Or is it a firefox bug to not recompute the relative widths (ex)?)

<h1 class="Sh" id="SYNOPSIS">SYNOPSIS</h1>
<table class="Nm">
  <colgroup>
    <col style="width: 13.00ex;"/>
    <col/>
  </colgroup>
  <tr>
    <td><b class="Nm">~/.ssh/config</b></td>
    <td></td>
  </tr>
</table>
<br/>
<table class="Nm">
  <colgroup>
    <col style="width: 19.00ex;"/>
    <col/>
  </colgroup>
  <tr>
    <td><b class="Nm">/etc/ssh/ssh_config</b></td>
    <td></td>
  </tr>
</table>

In lynx it displays fine.
