Thanks for the new page, @gRastello! I've left some comments below for you to review.

Suggestions seems good to me, applied to both English and Italian pages.

Hello again, @gRastello and thank you.

I see you are making a PR from a branch which has 16 commits, some of which were already incorporated in a previous PR and have nothing to do with the requested page addition. This makes it hard to understand which changes are going to be applied. Could you please rebase your branch on upstream/master to only keep the relevant commits?

I do agree on using "paragraph" instead of "sentence" since it makes more intuitive sense. However the official documentation as well as the man page do use the word "sentence" defining a sentence break as the end of a paragraph. Pretty confusing to be fair.

Also sorry for the mess I made with the branch but it should be fixed now.

@gRastello the documentation talks about sentences because it says that breaking lines is done preferring the end of sentences by default. That specific command I was commenting on adds two spaces between paragraphs though.

For example:

$ fmt -u <<< 'abc def. ghijkl.
> abcd. efg.
> hij.'
abc def. ghijkl.  abcd. efg.  hij.

You can see that two spaces are only used between paragraphs, not sentences (paragraph = group of sentences followed by a newline character).

Well, looks good to me 👍 thanks @gRastello 😄
