[v3 PATCH 2/2] reset: add tests for git reset -
From: Sundararajan R <hidden>

The failure case which occurs on teaching git is taught the '-' shorthand
is when there exists no branch pointed to by '@{-1}'. But, if there is a file
named - in the working tree, the user can be unambiguously assumed to be
referring to it while issuing this command.
The ambiguous case occurs when the @{-1} branch exists and file named '-' also
exists in the working tree. This are also treated as a failure case but here
the user is given advice as to how he can proceed.
Another potentially tricky case is when the file '@{-1}' exists. In this case,
the command should succeed as the user doesn't mention the file '@{-1}' and can
be safely assumed to be referring to the @{-1} branch.
Add tests to check the handling of these cases.
Also add a test to verify that reset - behaves like reset @{-1} when none
of the above cases are true.

Thank you for your feedback Torsten and Eric. I have made modifications suggested
by you. I have also acted on Matthieu's suggestions on the archive.
Please let me know if there is something else I should add.
I have also removed one irrelevant test from which we come to know of nothing new.
