>Description:
	Here is, what just happened:

	1) I logged in to a remote server over ssh;
	2) I started editing a file (an e-mail reply using elm);
	3) halfway through the Internet connection froze for 30 seconds,
	   but (foolishly) continued to type;
	4) impatient ssh broke the connection;
	5) I re-logged in immediately, and found there being no vi
	   process;
	6) Unfortunately, `vi -r' does not list any files.

Sometimes vi manages -- like when a file is still being edited at system
shutdown, so, perhaps, it would not be that difficult to fix...
