Merge branch 'jk/maint-null-in-trees' into maint-1.7.11
"git diff" had a confusion between taking data from a path in the working tree and taking data from an object that happens to have name 0{40} recorded in a tree. * jk/maint-null-in-trees: fsck: detect null sha1 in tree entries do not write null sha1s to on-disk index diff: do not use null sha1 as a sentinel value
