Blacklist @mods and several other JSDoc tags from wrapping.

[mprobst]

Summary

Limit the blacklisting to only apply when the tag is actually followed by a parameter in curly braces.

/** @mods {long.type.must.not.wrap} */

vs

/** @const this is a long description that may wrap. */

JSDoc tag reference here:

I'd vote for making this "@\w*\ *{". We have seen incorrectly spelled version and such of this in the past.

• Match \\w* for all JSDoc param tags.

Thinking again, I think the first "*" should probably be a "+", but not sure.

Ah. I tried that initially, and fooled myself into thinking that didn't work. Done.
