If the user runs a diff when there are modified files in the working copy,
they expect to be able to be edit the files in the diff viewer and save
the changes. When using difftool in file mode (i.e. diffing one file at
a time), this works as expected. However, when using difftool in directory
diff mode, the changes are not saved.
This commit teaches the directory diff mode to copy changes from the diff
viewer back to the working copy.
