Nemo - Show selection size after copy or cut

[HT-7]

If items are selected on Nemo, the bottom status bar correctly shows, for example:

2 items selected (2,4 MB (2.386.223 bytes)), Free space:…

If CTRL+C are pressed or copy is selected from the "edit" menu,

The 2 selected items will be copied if you select the Paste command

Notably, no selection size is shown anymore. It would be more convenient if the size were still shown:

The 2 selected items (2,4 MB (2.386.223 bytes)) will be copied if you select the Paste command

The same applies to CTRL+X (cut-and-paste move):

The 2 selected items (2,4 MB (2.386.223 bytes)) will be moved if you select the Paste command

It might seem like a minor thing, but many minor things put together make a big difference. I think it would take at most three minutes to implement this, so there is no reason not to do it.

I liked this idea.
