i18n-it: translate [OPTION]..., not [OPTIONS]...: keep the singular Since [OPTION]... is intended to mean more options, it was translated in Italian as plural. However the plural is conveyed by `...', so switch to the singular. This was also useful because for the '-o OPT' extdiff option, I have to translate `OPT' as a singular.

i18n-it: readd other lost accented characters The problem was introduced already in revision 9f9137cd83f5 by the original Italian translator, according to logs. This might be due to a bug in the program he used, "Lokalize 0.3", or maybe not - some accented characters exist also in that commit.
