Cannot unstage blank or renamed files

[liangkarl]

The reproduced steps are as follow:

1. touch test.txt and enter tig
2. In the status view, press u to add the test.txt
3. Now the test.txt is in stage view and it's useless to press u to unstage test.txt
4. The only way to unstage test.txt is git reset by typing this command manually.

What about 4. In the status view, press u to unstage text.txt ?

Uh, tig would show the message, fail to update files.

This message is from the stage view, switch to the status view (s).

[liangkarl]

Thanks. It's worked that unstage text.txt in the status view. However, I think it's quite weird that we couldn't unstage files in the stage view.

If possible, I'd like to suggest tig to correct this SW behavior with the lowest priority. :)

I'm not too optimistic, the stage view implementation is essentially based on using diff chunk headers and in this case, there isn't a full one.
