Linking to classes on call-seq does not work

[dLobatog]

I'm documenting a C file, say I leave a comment like this,

/*
 *  call-seq:
 *     Math.tan(Numeric : x)    -> Float
 *            

It gets parsed correctly, but the output HTML does not link to classes Numeric or Float.

I'm down to fix this, i'd appreciate a pointing finger to the relevant code though :)

I'm unsure if I want to allow this change. When you click on this part of the HTML output it shows and hides the source. Having it sometimes show or hide the source and sometimes navigate to other documentation is not a good user experience.
