reset doesn't reset a revert?

["Octavian Râşniţă" <orasnita@gmail.com>]

Hi,

Under Windows XP, using git version 1.6.4.msysgit.0, I have tried:

E:\lucru\git\k>echo foo > file.txt
E:\lucru\git\k>echo bar >> file.txt
E:\lucru\git\k>git init
Initialized empty Git repository in E:/lucru/git/k/.git/

E:\lucru\git\k>git  revert HEAD~

#Does anyone know what does this mean? So I've tried with HEAD^ instead.

E:\lucru\git\k>git  revert HEAD^

# What should I respond to the questions More?
#I've seen that no matter what I type, it adds to the "HEAD" and tells that 
that commit can't be found, so I just pressed enter.

E:\lucru\git\k>git status

#It seems that the revert commit was added successfully.

E:\lucru\git\k>type file.txt
foo
bar

#And it seems that not only the repository was changed, but the working 
directory also. Is it correct?

#Well, now let's say I discovered that this new commit was an error and I 
want to reset it.
#And I used HEAD^ because HEAD~ didn't work with revert.

E:\lucru\git\k>git reset HEAD^

E:\lucru\git\k>git reset HEAD~

#This time git reset resetted the latest HEAD.
#It seems that git reset wants the HEAD~ commit, while git revert wants the 
HEAD^ commit. Do you know why (or can I find an explanation for this 
somewhere)?

E:\lucru\git\k>type file.txt
foo
bar

#However, git reset modified just the repository and not the working 
directory.

I added the line baz in the file file.txt, commited this change and then 
reverted to the previous commit. This has also deleted the line "baz" from 
the file.
Then I resetted the last commit (the revert), however the line "baz" didn't 
appear in the file.

Is this something normal I should expect, or I am doing something wrong?

Thank you very much.
