More complaining:

In src/bogoutil.c,
        fprintf(stderr, "Option -%c requires an argument.\n", optopt);
prints garbage when using a long option.

(f.ex.)
% bogoutil --db-verify 
Option -�requires an argument.

Also, if I run --db-verify with a directory instead of the .db file,
% bogoutil --db-verify .bogofilter
zsh: 27557 bus error  bogoutil --db-verify .bogofilter

in contrast to
% db4.3_verify .bogofilter
db_verify: read: 0xeffff968, 512: Is a directory
db_verify: Metadata page 0 cannot be read: Is a directory
db_verify: .bogofilter: Is a directory

I do like the usage output of "bogoutil" even though it's missing
options that are present in --help.

I'll refine the zsh completion function for bogoutil further in the near
future.
