Environment


Platform ServicePack Version      VersionString
-------- ----------- -------      -------------
 Win32NT             10.0.19041.0 Microsoft Windows NT 10.0.19041.0

Windows Terminal v1.3.2651.0

Steps to reproduce

  1. Install the fish shell in Ubuntu 20.04 (apt install fish)
  2. Start fish
  3. Paste multiple lines of shell commands

Expected behavior

Like on a Linux desktop system, I would expect fish to show me all commands before they are executed. A confirmation by the user should be needed.

Actual behavior

Windows shows a paste warning, but the fish "security mechanism" is circumvented.

Windows Terminal seems to execute each line by itself instead of giving the whole pasted string to fish shell.
