Bug/Feature in Tabix?

[boguski]

I had posted this report on BioStars, http://www.biostars.org/p/68757/, regarding what I consider to be a bug in Tabix. If I query a single position in a tabix-indexed vcf file by using a region that is +/- 0.5 of the target position, the result contains neighboring positions if they appear within a few units of the target.

Am I using tabix beyond its intended scope? Does anybody else use tabix this way?

Tabix's author Heng Li (lh3) replied on BioStar - the limits should be integers, so yes, you're not using it as intended.
