This patch makes the first half of write_sha1_file() and index_fd() externally visible, to allow callers to compute the object ID without actually storing it in the object database. [JC demangled the whitespaces himself because he liked the patch so much, and reworked the interface to index_fd() slightly, taking suggestion from Linus and of his own.] Signed-off-by: Bryan Larsen <bryan.larsen@gmail.com> Signed-off-by: Junio C Hamano <junkio@cox.net> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
