need undelete function (Jeremy, what is your idea?)

This would however result in concertn about performance when this
option *is* used. Also, it does not avoid a (time costly) check
whenever a file is to be unlink()ed.
It also does not deal with archiving versions when a file is 
altered/overwritten
instead of deleted.
I guess any sort of undelete-functionality should be toggled with a 
#define of some sort if performance either way is an issue.
I don't think that the ease of coding is a valid argument here =).
