i18n-it: update mq translation
Significant updates were performed - when translating something, I tried to
choose a term and use it consistently everywhere possible, so here I translated
a lot of messages. Additionally, I use the mq extension a lot, and now I am
using the translation, so I will be able to translate it better.
i18n-it: general updates fuzzy synopsis texts
This patch follows the fix on the translation of [OPTION]... with other needed
updates on the same class of messages.
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.
