Changes since v2:

1. According to Documentation/CodingGuidelines

 write 'echo test >"$1"'
 instead of 'echo test> $1'

2. Add a SP after "#" to make sentence more readable.

3. When file present on-disk without modifications, add
test to make sure not only the two output must
match, they both must be empty.

4. Remove the useless test for HEAD:testfile.
