Hi!
I've made necessary changes to the code. Now it should look much better:)
New version of patch is inserted below.

Subject: [PATCH] Added empty VCARD N: parameter handling
Some of the devices are expecting that N: parameter in VCARD is always filled (by example Nokia BH-903)
When this field is empty (N:;;;;) then list of dialed/incoming calls on carkit is useless - carkit then shows only blank lines and it's impossible to determine who made call ( phone number are invisible too in this case)
If none of the contact fields is available, then setting telephone number as the first attribute for "N:" parameter.
Carkit will see that number as contact name - it is only used in case when none of more detailed contact information is available on the phone.

Hi Radek,
using git send-email would be a bit better here. Then we have the
patches inline.

The extra if clauses require two level of indentation. Otherwise you
can't tell which is part of the if clause and which is code.
Also it is strlen(...). No extra space.
And I would prefer to split this into an extra function just doing this
test. This if clause is too big.

So I prefer the whole thing like this:
/* if all fields are empty we're using first phone number as name */
if (required_fields_present(contact) == FALSE) {
struct phonebook_number *number = contact->numbers->data;
vcard_printf(vcards, "N:%s;;;;", number->tel);
return;
}
vcard_printf(vcards, "N:%s;%s;%s;%s;%s", contact->family,
...
This way it is a lot easier to read and understand what is the special
case and what would be the default.
Regards
Marcel
