If there are html tags in the description of a snippet,
the page that shows the snippet summaries may be
scrambled, because html tags have not been escaped. It
seems to be solved by changing line 31 of file
echo substr($d, 0, 100)."...";
echo htmlentities(substr($d, 0, 100))."...";
not sure if this causes other problems, but it solves
this particular problem for me.
