1) If I need these lines in zsh 2) If they are needed, how do I keep them from throwing an error 3) How I track down these errors and get rid of them without restarting the shell?
OK, I did a 'exec zsh' and that has fixed the errors. I've left the lines commented out and tab completion is still working.
I'm probably good. But if someone could reassure me, I'd appreciate it.
