'Raw' tokens in link module do not output their content

Problem/Motivation

Using the Raw uri, Raw title, or Raw options tokens for a link field instance does not output those contents -- it prints a number instead.

Steps to reproduce:

1. Add a link field to a content type and create one or more nodes of that type with links.
2. Create a view to display this content type using fields.
3. Configure the field and choose the "rewrite results" option.
4. In "Override the output of this field with custom text" use any of the "Raw" tokens (uri, title, options).

Expected result: Token will output the raw value: URI, link title, or link options.

Actual result: Token outputs a number (0 in one case; 1 in another -- it doesn't appear to be the node/entity ID but I'm not sure what it is). It also exists whether or not you check the "URL only" or "Show URL as plain text" options.

There are probably other ways to expose the contents of the token without creating a view, but this was the context in which it came up for me.
