Hash: SHA1

We only deal in canonical sha1s.

The sha1 we store in the dirstate is the canonical form.

So path_content_summary is doing:

st = os.lstat(path)
size = st.st_size

sha1_and_other_info = self._check_the_hashcache(path, st)

In other words, it is ignoring the data stored in the dirstate when
returning the size of the file. I believe we store the size into the
dirstate in such a way that we could return it, rather than looking at
st.st_size. Though I'm not positive. (We do for old revisions, but I
would have thought we wouldn't for the *current* column.)
