<h3>Fix problem with numeric soft events</h3>
<p>Changing from numeric to named soft events introduced an incompatibility
when a numeric event is converted from a DOUBLE, e.g. from a calc record.
To make named events backward compatible to numeric events, the logic has
changed as follows:</p>
<ul><li>Leading and trailing spaces are strippd from the event name
<li>Empty event names are no events
<li>If the event name can be converted to double:
<ul><li>If the double is not finite (inf or nan) it is no event.
<li>If the double truncated to integer is between 1 and 255
it is a numeric event. Its name is changed to the decimal
integer representation.
<li>If the double truncated to integer is 0 it is no event.
</ul>
<li>All other cases are named events
</ul>
<p>Also <code>scanpel</code> has been modified to accept a glob pattern for
filtering and to show events with no connected records as well.</p>
