Amend does not automatically refresh working directory
To reproduce the behavior:
In TortoiseHG Workbench select a repository and click on Working Directory. Make change to arbitrary file.
Select "Amend" instead of "Commit". In status window changed files will be shown.
Amend the changes.
Status window still shows that files are changed (need to manually click "Refresh file list" button).
The behavior have been introduced in 2.7
