[PATCH] t7111: check that reset options work as described in the tables

[Christian Couder <chriscool@tuxfamily.org>]

Some previous patches added some tables to the "git reset"
documentation. These tables describe the behavior of "git reset"
depending on the option it is passed and the state of the files
in the working tree, the index, HEAD and the target commit.

This patch adds some tests to make sure that the tables describe
the behavior of "git reset".
