And is it intended that (clean) merges are shown?

Path limiting simplifies history, and might linearize it (i.e. merges
become non-merges).

Actually, path limiting, when it simplifies merges, will *only* simplify a 
merge when one of the parents was identical to the end result (which 
implies that the other parents were obviously not interesting as far as 
the end result is concerned!).

But that has a secondary effect: such a merge will then (by definition) 
always be simplified away, since the simplified merge no longer makes any 
changes to the set of files in question!

So "merges become non-merges" is not really true (except in a very 
internal sense that will be invisible to the outside). They either stay as 
merges (end result is different from any of the parents on their own), or 
they go away entirely (end result is identical to one of the parents and 
the merge ends up not containing any change atr all).

This explanation may, of course, be more nit-picking than anybody really 
wanted to hear.
