A modern doexpire will itself delete history.o before it starts getting
serious about space shortages.  You've got a seriously-old copy of C News.

It's just the old history file.  It can be useful for troubleshooting.
Otherwise, its only real use is that it ties down about the amount of
space that doexpire will need for the history rebuild, in effect reserving
it to increase the chances that doexpire won't need to resort to -r.
Modern doexpires automate its removal already.
