Previously there was always a short fall when scaling delimiters, even if the user requested a specific size. This is no longer the case; the short fall is only present in the default for `lr` (`x => x - 0.1em`), and is the reason for the updated tests - the size of the delimiters is now actually what was specified in the size argument. This also makes the default for `lr` much clearer to the user. A slight hack was used by exploiting the `name` property in the `func` attribute macro so that the default value in the docs for `lr.size` would clearly show what the default function was (instead of just its name `default_lr_size` which is meaningless and inaccessible to the user).
