Well, It's a scenario I found in the mailing list a while ago. Someone
explained that he made tags, but he included files that weren't
versioned earlier.
The example he gave was: They build the binaries. They normally don't
version them, but when they create a tag for a new release they do. So
they create a tag with both the source files (for the new release
version) that are already present in the repository and the newly
generated binaries that aren't yet versioned.
Of course when you commit all files are versioned.

But... thinking about it... "adding the binaries to the tag" may be a
separate action (done after creating the tag) and in that case '5' is
not a valid concept. (Need some help here ;)

"Tagging the working copy, e.g., after a successful build, involves
copying a directory in the repository, *and* committing all the working
copy modifications to the copy. In this type of tag, the copy contains
some information found nowhere else in the repository, so it can't be
represented by a URL and revision."

And that is exactly what I meant to say. Thanks :D
