Browsing Italian translation

Translators: This is the string used for displaying the
* folder names in folder trees. The first "%s" will be
* replaced by the folder's name and "%u" will be replaced
* with the number of unread messages in the folder. The
* second %s will be replaced with a "+" letter for collapsed
* folders with unread messages in some subfolder too,
* or with an empty string for other cases.
*
* Most languages should translate this as "%s (%u%s)". The
* languages that use localized digits (like Persian) may
* need to replace "%u" with "%Iu". Right-to-left languages
* (like Arabic and Hebrew) may need to add bidirectional
* formatting codes to take care of the cases the folder
* name appears in either direction.
*
* Do not translate the "folder-display|" part. Remove it
* from your translation.
