Bug with split on large single token markup

[jfroelich]

For example:

/**
 * @idontknowhyanyonewoulddothisbutiguessitcanhappenthisiscrazylong
 */

In this case the jsdoc tag gets split. we should never mutate a jsdoc tag itself. We should bail.

Then there is a separate but very similar issue.

/**
 * @sometag someverylongsingletokenherethatcausesoverflow
 */

Right now the behavior is to move the tag text after the tax to the next line. Is that correct? The tag is being treated as a token itself. Maybe we should be detecting jsdoc lines and tokenizing them differently. Maybe the appropriate behavior is to hard break the large token in the tag's description area? Because I think we if move the token to the next line, that breaks the link between the tag and the description sometimes? Uncertain.
