file transfer source and target are impossible to retrieve from information in file transfer dialog (name isn't sufficient)

When the user copies directory a into directory b the file transfer dialog only displays information that is moves or copies a into b rather than /path/to/a into /path/to/b. This causes the following deficies:

  * If the user copies /path/to/a into b and /another/path/to/a into b the file transfer dialog become unnecessarily complicated
  * If the user copies 20 large files over night while sitting in a bar and having dring and checks the dialog again in the morning he_she has no idea which files are about to be copied.

Displaying the full path should be the default because there's no usecase for information loss. In case it's desired to keep the transfer dialog small, it'd be good to have a collapsible pane for extended information or a collapsible pane for each file name.

Of course the dialog label has be tested for well working line breaks (it should support arbitrary long pathnames in order to cover any filesystem that will ever be invented) so that there's no case where label in the form of

  * `copying /the/very/long/path/t...` or
  * `copying /the/very/long/path/to/the/file into /the/other/very/long/p...` or
  * something similar

occur.
