As far as I can see, the whole reason for the "xovergroup" variable
is to avoid re-reading the overview file over and over again. Setting
xovergroup to NULL after group selection and reading the overview
file would therefore be equivalent to removing "xovergroup" from
the code altogether. (While this would make the nntpd somewhat
slower, I think that with the speed of current HDs it would not slow
down the nntpd significantly.)

Under that perspective, getxover() has to be called every time something
from the .overview data is requested. Or do I overlook something?
