Copy and paste includes newline characters

[Loomsday]

First of all, many thanks for MyCLI.

After configuring the prompt and prompt_continuation to my liking, I am only left with one tiny but annoying issue, namely that copying from the MyCLI prompt causes the newlines at column 80 in the terminal window to be copied along with the SQL statement:

Copying and pasting the statement results in:

i.e. after pasting I have to edit the string and remove the inserted newline characters by hand.

Is this something that can be fixed on the MyCLI side, or is that perhaps an issue with xfce4-terminal?

Many thanks again!
