 This filter ensures that all data written to the DBM file is null
 terminated. This is useful when you have a perl script that needs to
 interoperate with a DBM file that a C program also uses. A fairly common
 issue is for the C application to include the terminating null in a
 string when it writes to the DBM file. This filter will ensure that all
 data written to the DBM file can be read by the C application.
