Edit the View Ticket page and find:

<verbatim>
<tr><td align="right">Version&nbsp;Found&nbsp;In:</td>
<td colspan="3" valign="top" bgcolor="#d0d0d0">
$<foundin>

</verbatim>

Then change it to:

<verbatim>
<tr><td align="right">Version&nbsp;Found&nbsp;In:</td>
<td colspan="3" valign="top" bgcolor="#d0d0d0">
<th1>
wiki "[$foundin]"
</th1>

</verbatim>

This will use Fossil's builtin wiki rederer to create to the commit whose UUID is in the found-in field.
