Thank you very much for posting that bitfish. I've since added it to my .zshrc file.
And check you backups (I'm sure you have a backup

)
Go to the root dir of your backup drive and do a:
#find ./ -name .bash_history -exec rm {} \;
#find ./ -name .viminfo -exec rm {} \;
or even better:
#find ./ -name .bash_history -exec wipe -f {} \;
#find ./ -name .viminfo -exec wipe -f {} \;
(You need
wipe installed)
