This patch provides ability to pass -v/--verbose option to the
git hash-object command. hash-object will print not only hash,
but also file path of a file from what hash was calculated.
It can be useful in scripting, especially with --stdin-paths
option.
For example:
$ git hash-object -v test
e69de29bb2d1d6434b8b29ae775ad8c2e48c5391 test
