Turning on HTML is done in the Calendar Administration > Calendar Settings by selecting Allow HTML: (o)Yes ( ) No.
The rest (ie. entering the needed HTML formatting tags) is up to you.
IF you are so inclined, the script can be modified to automatically add line breaks. You can find a couple of previous forum messages that discuss that topic in the 'Links' section of the Unofficial CalendarScript - Mods and Plugins site' under "Event display mods".
