Yes, I updated to trunk -r2894 right before applying the patch. No other 
patches were applied.

Could be. In any case, it would be nice to get rid of these bogus 
warnings, so that the real coastline errors can be fixed. Yes, the 
errors could be checked with the JOSM Validator, which implements some 
checks. AFAIU, the neither the JOSM nor mkgmap checks are subsets of 
each other (you need to run both to get all checks).
