[Bug 1925823] Re: losts or misinterprets the newline character coming from mouse paste

[Péter Prőhle]

In addition to the correct behaviour of the GNU bash, I will not get
that disturbing fancy behaviour of the Ubuntu 21.04 version, that

instead of executing the command

the dropped command is shown in reverse video.

Hence the bug in question is clearly an Ubuntu re-packaging issue.

** Summary changed:

- losts or misinterprets the newline character coming from mouse paste
+ Ubuntu version of BASH losts or misinterprets the newline character coming from mouse paste

Title:
  Ubuntu version of BASH losts or misinterprets the newline character
  coming from mouse paste

Status in bash package in Ubuntu:
  Confirmed

Bug description:
  Quiete a few experients shows, that bash misinterprets the newline-
  character coming from mouse paste, while in the same terminals the
  emacs or vim or alpine and many other character oriented programs
  interprest correctly.

  The problem is specific to the situation when we are at a bash prompt
  of a new version of bash we got in Ubuntu 21.04. As soon as I invoke
  an ssh session, the interpretation of the newline-caharcter becomes
  correct, since the remote older bash interprets correctly.

  >>> Newline bug of first kind:

  If there is a complete bash command with terminating newline in the
  cut and paste buffer,

  and it is pasted into a gnome-terminal,

  then the command is *not* executed, the newline is ignored by the
  terminal.

  >>> Newline bug of second kind:

  If I prepare a bash command say

          cp  target-directory

  and I collect into the paste buffer "source-file newline-character"

  and I drop it IN BETWEEN the prepared "cp" and "target-directory"

  then the result is wrong:

          instead of interpreting the newline-character as "push enter"

          the command is broken into the followint 2 lines:

                  cp source-file

                  target-directory

  and I get an error message about missing target specification.

          cp: missing destination file operand after 'source-file'
          Try 'cp --help' for more information.
          bash: target-directory: Is a directory

  I found better to make this original bug descripton more informative.
