The problem is not which function to use here to make a link to the 
current page.
If you read further the problem becomes clear:

In short:
The TYPO3 link functions include a querystring in the action attribute 
of a GET form (id plus optionally others):
- without url rewriter (e.g. realurl) this will be stripped by the 
browser and only the fields in the form are added to the url
- with a url rewriter the parts of the querystring which are mapped in 
the realurl configuration are used to build the url so they will survive

Alternatively, include all parameters (including id) in the form as 
hidden fields:
- without url rewriter this works correctly
- with url rewriter the form will go to a url which is not rewritten (so 
visitor will see an "old type" url (with id=xx...))

The only (ugly) solution I can think of at the moment is to let TYPO3 
build the url, let PHP parse it, put the querystring parts in the form, 
rebuild the rest and use that as the action. I hope there is a prettier way!
