NAME
confirm-paste - ask for confirmation before pasting control characters
DESCRIPTION
Displays a confirmation dialog when a paste containing control characters is detected.
This is mostly meant as a defense-in-depth mechanism to protect against the common web browser bug of you selecting some text but the browser pasting a completely different text, which has some attack potential.
It can also be useful to prevent you from accidentally pasting large amounts of text.
