David, it looks like tildeexpand() isn't being called due to the
wordlist code reorganization in 0.91.0.

> The most recent release of bogofilter has completely ceased working.  Error message is (roughly) '~/.bogofilter, no such directory'.  Attempts to recreate/retrain the database result in directories called "~" strewn about the filesystem.  0.90 works perfectly.  It appears that 0.91 doesn't correctly interpret the ~ character as 'user's home directory'.
