On the contrary, to me this is acceptable (or even "a good thing") 
because a patch introducing the first use of a so-far-unused argument 
deserves a more careful review.  In fact, if we were using C++, 
check_for_block_signature should have been static.

The cases where the "this" argument is unused in a method should stand 
out as possible bugs, as is the case with the parse errors in the JSON 
parser (which _is_ a bug, as the caller cannot intercept error messages 
right now).  check_for_block_signature is not one of these.
