Option 'Close dialog when all changes are committed' does not work properly

[crypto-rsa]

Steps to reproduce:

1. Make some changes in the repository
2. Open the commit dialog
3. Make sure that the Close dialog after each commit option is off, Close dialog when all changes are committed is on and Refresh dialog on form focus is on
4. Type in some commit message but do not stage anything
5. Click commit and click Yes to stage and commit all unstaged files

After the commit is performed, there are no uncommitted changes in the repository so according to the settings the dialog should close automatically - but it stays open.

I believe the problem is that in step 5, the unstaged file list is not updated (it still contains all the original changes) and so the value of the AppSettings.CloseCommitDialogAfterLastCommit option is ignored (see line 954 in method DoCommit).
