It's worse because of commutation. If I do
sed --in-place 's/foo/bar/' *.c
I can then visually inspect the diff, be satisfied that I haven't
accidentally missed out 2*foo (false negative) or replaced fooBaz with
barBaz (false positive).
But if I make a darcs replace patch, and then later merge in someone
else's older code that *adds in* a 2*foo and a fooBaz where there
weren't any before, then maybe there will be NEW false positives or
negatives that I didn't notice, because the replacement is effectively
being done on code I never checked.
