Title:
  Can't copy and paste more than 4kB into a terminal

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  I am unable to copy and paste more than 4kB of script into a terminal
  (e.g. gnome-terminal, xterm). I have been encountering this issue for
  nearly a decade now (across multiple distributions, including Ubuntu
  14.04 LTS). I believe it may relate to kernel parameter
  N_TTY_BUF_SIZE. A similar problem appears to have been reported here;
  http://comments.gmane.org/gmane.linux.kernel/1253720.

  Use case;
  1. The user has a large semi-automated script (e.g. 2000 line deployment instructions.txt; which do not justify full automation*).
  2. The user wishes to copy and paste one or more automated sections of the script into a terminal (e.g. gnome-terminal, xterm, etc) while following the self-contained instructions.
  3. Those automated sections of the script may contain more than 4kB worth of data (spread across multiple lines)

  Actual behaviour;
  - the script being pasted into the terminal is corrupted, then executed

  Expected Behaviour;
  - the script is successfully pasted into the terminal, then executed

  I have reported this issue because it is not intuitive that the system
  should behave like this. While now that I know it may be a fundamental
  limitation of current (/prior) Linux kernels, I will ensure to work
  around it in future activity. However, it is feasible that someone
  else may encounter this issue before it is rectified. Every time this
  issue occurs there is a possibility of system corruption (depending on
  the precise script being copied to the terminal).

  Perhaps a patch has already been released? Or if this issue should be
  reported elsewhere, feel free to recommend an alternative forum.

  * e.g. because the self-contained instructions only need to be
  executed ~10 times across the product life cycle, taking into account
  the fact automation time is a function of a) how busy the user is /
  spare time they can devote to subsystems, and b) the level of
  robustness required: automatically editing files which may have been
  significantly updated between deployments is not necessarily safe.

  Cheers -

  Richard
