Description of the new feature/enhancement

Simple feature quest, to add an option to automatically trim spaces and/or new lines from pasted text.

I'm constantly copying stuff, pasting in the terminal and having to go with my arrow keys to erase unnecessary chars so that my commands work.

Proposed technical implementation details (optional)

We can have these options:

1. Trim new lines
2. Trim spaces

a) Trim leading
b) Trim ending

Maybe it should display as two ComboBoxes:

New line trimming: Disabled/Leading/Ending/Both
Space trimming: Disabled/Leading/Ending/Both
