with the currently implemented logic, the environment variable has two
different impacts: (1) it sets the `user-emacs-directory' variable,
and (2) it changes the logic used to determine the init file. There is
currently no `let' form encompassing the whole `command-line'
function, so I had to either
1- add one (which might be the most correct implementation, but
generates a very large patch for mostly unchanged lines)
2- define a global variable (which seems unnecessary), or
3- call `getenv' multiple times.

I chose the latter, but am perfectly open to rewriting the
implementation if you feel it would be better.
