So to conclude our discussion, plan for new feature is
- add "this" as keyword to produce links to same page
- skip unneeded processing in typoLink() function (i.e. calling to 
getPage_noCheck(), getPage(), getMountPointInfo(), 
getClosestMPvalueForPage) if TSFE->id == typolink.parameter

I'll try to submit RFC with the patch soon.
