group writable __db files

[Fletcher Mattox]

Hi,

I need for the __db lock files to be group writable, but seem
unable to make that happen with umask.  I even added a umask(002) to
the startup code in bogomain.c.  But after a while, the __db files
are mode 0644 again.  Any idea what I'm doing wrong?  This is
bogofilter 0.93.1, by the way.

Thanks
Fletcher
