As Barmar points out, this previous paragraph is wrong (not much thought went into
my afterthought). I had forgotten that as part of expunging a file LMFS zeros out
the first header record (called the R0) record, which makes the data of the file
irretrievable. I probably forgot about this because I consider it a bug; if it
weren't for this, what I said would have been true.
If the salvager *could* unexpunge files, it should only do so as an
option. I wouldn't want my periodic salvages to go around unexpunging
all the deleted files on the system.
