vcf2fasta on single sequence fasta - insert N for deletions

[GuitCos]

Hello,
I was wondering how the vcf2fasta tool deals with deletions of the type :
Contig284 3255757 . TGCC T 80.01 . AC=1;AF=1.00;AN=1;DP=2;FS=0.000;MLEAC=1;MLEAF=1.00;MQ=34.00;QD=31.35;SOR=0.693 GT:AD:DP:GQ:PL 1:0,2:2:90:90,0

Is it possible to instruct vcf2fasta.py to replace the missing nucleotides with 'N's, as it seems it does not do it by default. Or maybe I have missed something ?

Thank you,
