If you triple click on a line, it will highlight the line, but also the newline character, so when pasting, it would paste as:
``` this is a line of text
```
instead of
``` this is a line of text ```
Would it be possible/desired to add an option to change this behaviour, so it only copies the text and not the newline? One example of when this can be annoying is copying commands from a file, having an extra newline isn't needed.
