I have added 6 tests to check for the following cases:
git reset - with no @{-1}
git reset - with no @{-1} and file named -
git reset - with @{-1} and file named @{-1}
git reset - with @{-1} and file named - 
git reset - with @{-1} and file named @{-1} and - 
git reset - with @{-1} and no file named - or @{-1} 
The 1st test with no previous branch results in the error
The 2nd,3rd,4th and 5th result in the ambiguous argument error 
The 6th test has - working like @{-1}
