I noticed that somewhere ae has started taking over as the default
editor in place of vi/vim.
I have tried placing EDITOR="vi" in the /etc/profile line but it
doesn't always work.
CVS was defaulting to ae.
crontab will sometimes default to ae.
How do I fix this? ae is not at all what I am accustomed to and was
rather dismayed to find it so prevelant on all my systems overnight.
