It _might_ be worth mentioning that you can compare two arbitrary
files using

   git diff [--options] <blob1 sha> <blob2 sha>

where <blob sha> can be entered as <tree-ish>:<filename>, usually
<commit>:<filename> (<filename> is HEAD:<filename>) to compare blob (file)
from a named tree/from a given commit, or as :<stage>:<filename> (or
just ::<filename> if file is not in merge conflict) to compare blob (file)
from an index.

If I understand correctly there is currently no way to compare files from a
working tree, not to mention files outside working tree
(including /dev/null) with that syntax.
