	* spam : changed system calls, using a list of arguments instead
	of a single string (fixes problems with spaces in names).

	* spam (EditDenyFile): new function which runs the editor, trying
	first to use environment variables EDITOR and VISUAL before to
	fall back to "vi".

	* added the file ChangeLog.
