CentOS 7 emacs 24.3 -bash: __emacs_complete_pre_command: command not found

Auto complete is problematic

[robnagler]

This only happens when su'd to another user. Emacs creates functions in the shell, and assumes they are there when you start another shell:

$ compgen -A function __emacs_c
__emacs_complete_pre_command
__emacs_complete_prompt
__emacs_complete_recover_prompt
__emacs_complete_wrapper
