Docs for add --tilde seem to be incorrect

[swrobel]

The docs say:

For example, yarn add [email protected] --tilde would accept 1.2.9 but not 1.3.0

which would lead me to believe yarn would add foo": "~1.2.3" to package.json, however it adds foo": "1.2.3" (no ~) instead. It seems that adding an @version will cause yarn to implicitly use the --exact flag ... unless I'm missing something here.
