The very earliest versions of Git did track the full mode, but that turned out to be annoying (you'd record useless changes caused by umasks of different committers). It was changed in e44794706e (Be much more liberal about the file mode bits., 2005-04-16), which is quite early on. :) We do use the mode bits for other things, too. Subtrees are 040000, symlinks are 120000, and submodule "gitlinks" are 160000. -Peff
