pip autocompletion should silence of KeyboardInterrupts

[anntzer]

• Pip version: 8.1.2
• Python version: 3.5.2
• Operating System: Arch Linux

Description:

pip uninstall <TAB> quickly followed by Ctrl-C causes a traceback (associated with the KeyboardInterrupt) to be printed. This traceback should arguably not be displayed.

A simple fix would be to change pip completion --zsh (and similarly --bash) to

# pip zsh completion start
function _pip_completion {
  local words cword
  read -Ac words
  read -cn cword
  reply=( $( COMP_WORDS="$words[*]" \
             COMP_CWORD=$(( cword-1 )) \
             PIP_AUTO_COMPLETE=1 $words[1] 2>/dev/null ) ) # note the redirection.
}
compctl -K _pip_completion pip
# pip zsh completion end

I didn't succeed in reproducing this issue with pip uninstall but I was able to interrupt pip freeze quite successfully

Can you include the traceback in the issue so others can see what the problem is?
