Yes, the patch prints out the results for *all* ways with log level 
SEVERE. This should enable you to check manually which rules are used 
for which way.
"Use line rules only..." means that only the lines style file is used 
for this way.
"Use both rules for..." means that the lines plus the polygon style file 
is used.

Ok, I should have explained that more in detail.

As far as I have understood you want to distinguish in your lines file 
if a way is closed (use continue statement) or a way is not closed but 
will automatically be closed by mkgmap (do not use the continue statement).

So your line rules will be:
waterway=canal & natural!=water & mkgmap:autoclosing!=true  [0x1f 
resolution 23 continue]
waterway=canal & natural!=water & mkgmap:autoclosing=true  [0x1f 
resolution 23]
