Currently we process pointers in a rather lax way and accept a variety of non-canonical pointers, such as those with CRLF line endings or a size value of 0 (which should be an empty file instead). However, we have a flag to indicate whether the pointer is canonical when parsing it, so let's add a --strict flag so that we can allow people to reject non-canonical pointers. Note that while strictness is not the default, we add a --no-strict flag as well so we can allow people to use it now and change the default at a later time (probably 4.0).
