[ale] OT: recover Safari browser history

Not wrong, just optimistic. :-) a deleted file is different from a
rewritten empty file. Especially troublesome if the old file and new
file occupied the same number of blocks and/or inodes on the drive. 

Ah, yes. I understand now. For some reason, I was thinking of the cache.
