[turba] Last name prefixes

[Jaap Winius]

Hi folks,

Recently I migrated from Horde 3.1.5 to 3.3.8 and saw that many  
changes had been made to the turba database. The number of fields per  
record went from 20 to 45, but I would actually liked to have seen at  
least one more. Specifically one for last name prefixes. Here's a few  
examples:

   van Veen
   de Silva
   von Braun
   van den Berg
   de los Santos
   le Grand
   di Cosimo

Such last names are used across much of Europe, and I guess Central  
and South America as well. However, when such last names are sorted,  
the prefixes are almost always ignored. So, "von Braun" is found under  
the "B" instead of the "V" as it typically is in the United States.

Unfortunately, like most address databases turba currently ignores  
this convention. As a workaround, I find myself now adding the last  
name prefix to the first name field, for example:

    First name: John de
    Last name:  Groot

But, this is not correct. I would rather that it be like:

    First name:       John
    Last name prefix: de
    Last name:        Groot

Has this idea been considered before? I'm sure very many European  
Horde users would appreciate this additional field.

Cheers,

Jaap
