bcftools norm --atomize does not split up a SNP followed by an insertion

[0xaf1f]

I have a variant record that looks like

1       3552597   .       C       GGGG

Following bcftools norm --atomize ... (v1.16), it remains the same. I suppose this is an odd case, as the expected output for making them independent records would be the somewhat unintuitive

1       3552597   .       C       G
1       3552597   .       C       CGGG

I think it's a sensible expectation. I am trying to make a SNP matrix for a phylogenetic tree and this sample is not getting grouped with others that just have the C->G SNP when I do bcftools merge.

That's a fair point, addressed now by 1f50f07. Thanks for the issue
