These two nano patches add the ability to use javascript: 
style location bar urls (sometimes known as bookmarklets) 
to konqueror.

As an example, try "javascript:window.resizeTo(800,600)"
Konqueror will "magically" resize itself.  This URL can
then be bookmarked giving a simple way to set the window 
size. Several thousand other uses for this are available.

David Faure mentioned possible security issues with this
patch, but, well, I can't really think of any :)

My TODO list: (to add to the one in the src)
   make sure that the executeScript is just ignored if javascript is disabled
   ask waldo if some kiosk option should be added
   make it possible to use javascript urls without needing a current page
      - i.e, somehow reuse the about:blank code
   display a security warning when executing a javascript: url (with tickbox to disable)
   come up with some really useful bookmarklets

mvg,
Alex who's gonna miss the start of buffy cus he got carried away with the hack :( ... :)
