Currently, we do not catch when the dash separating a parameter name from a parameter description is bordered by more than one whitespace character. We should enforce only one whitespace character on either side of the dash. So the following is good:

/**
* ...
*
* @param {number} x - input value
* @returns {number} output value
*/

and the following should be disallowed

/**
*
* @param {number} x    -     input value
* @returns {number} output value
*/

In principle, we could have up to three different lint rules:

1. enforce number of whitespace characters before dash
2. enforce number of whitespace characters after dash
3. enforce a specific character (e.g., -) to be used to separate a parameter name from a description

We could also have another lint rule for enforcing that a dash should not separate a @returns annotation from its description. This should likely be its own RFC.
