I kind of assumed that if you are debugging and suspect you might end up
in this situation, you set the variable in the debugger before starting
Emacs.  If you forget this, you are hosed of course, so a default off
for uninstalled is a good idea.

What is the proper way to check for installed/uninstalled Emacs?
