Before doing a diff/meld you should normalize the vcf data e.g. with
the following commands (in an empty directory):

csplit your-address-file.vcf /^END:VCARD/ {*} >/dev/null
for i in xx*; do 
 name=$(grep "^N:" $i | cut -d\; -f1-2 | sed 's/^N:;*//;s/;/_/')
 cat $i | 
  tr -d '\r' | 
  sed -Ez 's/(BEGIN|END):VCARD\n//g;s/\n //g' | 
  sort | 
  sed -z 's/^/BEGIN:VCARD\n/;s/$/END:VCARD\n/' >"$name.vcf"
 rm $i
done
cat *.vcf >$$
rm *.vcf
mv $$ addr.vcf

The addr.vcf file is sorted according to the fields and the address-
entries (field N). You then can do diff/meld and merge as you like.

I have two contact lists, which are very similar but not quite the
same. What's the best way to combine them?
