Yes, but you shouldn't have to do that. In fact, there's a number of
semicolon for additional performance data, and each additional part is
optional as well as the ; (if there's is no more parts).

see:
http://nagiosplug.sourceforge.net/developer-guidelines.html#AEN201

The spec is:

'label'=value[UOM];[warn];[crit];[min];[max]

so for example if you have only max to show, it will look like:
20x=94.71%;;;;100

But if you really want to remove any extra trailing semicolon, you can do:

$out =~ s/;+(\s|$)/$1/g;

Or keep the last one:

$out =~ s/;+(\s|$)/;$1/g;

This shouldn't affect performance data parsers at all.
