Thanks for fixing this! Do note that now that the message is a full "%1 event"/"%1 events", the comment for translators is not really relevant anymore:
196 + // TRANSLATORS: the first parameter refers to the number of all-day events
197 + // on a given day. "Ev." is short form for "Events".
198 + // Please keep the translation of "Ev." to 3 characters only, as the week view
199 + // where it's shown has limited space
200 + return i18n.tr("%1 event", "%1 events", events.length).arg(events.length)
FWIW, from a translation POV, it is fine to keep the short form, it's just that it needs to use plural forms (eg. i18n.tr("%1 Ev.", "%1 Ev.", events.length) is good enough if you need it to remain short text).
