dead lines in dig_att files

Is there any reason to drag along all of the lines in a dig_att file that
are associated with deleted lines? I have used v.clean to rid my dig file
of about 1000 lines, but the dig_att file is still the same length, with
lower case "l" replacing the upper case "L" for deleted lines (it appears).
Should v.clean also clean the att file?

Thanks

I'm not sure (can't think of any reason), but you can do the following:

% egrep '(^A|^L|^P|^E)' $LOCATION/dig_att/file > /tmp/$$ ; mv /tmp/$$ \
    $LOCATION/dig_att/file

if you definitely want to get rid of them.
