[PATCH] Use SHA1 for git-update-cache --refresh
[PATCH] Use SHA1 for git-update-cache --refresh

Change git-update-cache --refresh behaviour to use sha1's rather than
comparing byte by byte.

[JC demangled whitespace from the posted patch himself because he
 liked it so much.  Also adjusted to the index_fd() interface
 slightly done differently from the original one.]
