Allow "Ignore..." command for "just forgotten" files
Forgotten files (i.e. Removed but present) don't present the "Ignore..." command in their context menu in Commit Dialog. They should, so we don't repeat the error of adding them ;-)
Steps to reproduce:
- Add a file, commit.
- Run the "Forget" command on the file. It shows with status 'R' in the Commit Dialog.
- Open the context menu again, no "Ignore..." command.
