Feature request: Turn off header numbers when using -H

[ejgardner-insmed]

Hello,

The -H feature in various bcftools subcommands (e.g., query, +split-vep) is useful, but it also prints the column index (e.g., '#[1]CHROM') which can make it difficult for downstream processing with other tools. I recognise that most bcftools / htslib commands know how to handle the adjusted header, but it would be nice if there was a flag to disable it.

Thank you!

This is now possible by giving the option twice, -HH will result in #CHROM instead of #[1]CHROM.
