Hitting return on trash-restore without entering a number results in unclear behavior

When restoring files using trash-restore, users are asked which files they would like to restore, and are able to enter a number. If there is only one option, 0 is the only input option. The behavior is unclear when return is pressed, without entering a number. With no input other than hitting enter, the program exits, printing out nothing, with a successful exit code (0). It is unclear whether or not the file is restored.

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.
A few options to mitigate this confusion are:

• exit with a non-zero exit code -- this would show that the trash-restore has failed to restore any files
• print out "No files restored" or something similar to the console -- this clarifies that nothing happened
• describe the behavior of simply pressing return when options are given in the prompt (i.e. "What file to restore: [0..9] (hit return to cancel):

In my opinion, the best option would be to implement all three of my proposals.

Hi @lukasvrenner ,
About the options you considered:

• exit with a non-zero exit code -> I prefer to still use the zero exit code because is ok not to restore anything.
• print out "No files restored" -> good, I just merged your code
• (hit return to cancel) -> interesting, if you want (or anyone other) you can push another PR with this addition

Thank you
