Fix ratio limit in documentation
Fix ratio limit in documentation

The value of ratio isn't limited to 0-1, which can be checked in the two first links below. It probably was a mistake caused by copy-pasting the documentation of "progress", which is limited to 0-1. The commit where this extra info was added is the one in the third link.

As this value is the result of something like `uploaded / max(1, downloaded)` it never get's to `Infinity`, so it's limited by 0 and `uploaded`. Without the ` || 1` part it would be limited between 0 and infinity.
