Duplicate repository entries shown on package "Versions" page

[fingolfin]

Looking at https://repology.org/project/gap/versions I see "nixpkgs stable" and "nixpkgs unstable" each three times. And at least as far as I can tell, there is no difference between the duplicate entries.

Looking at https://repology.org/project/gmp/versions, "Amazon Linux 2" is listed twice. "OpenBSD Ports" lists it four times. "Scientific Linux" has two versions; one listed twice, one three times

Mind you, I am only mentioning examples where the package list gives exactly identical descriptions. That's why I don't mention e.g. GNU guix where
GMP has two entries, but for different version (6.1.2 and 6.0.0a).

If there are actual difference between these duplicate entries, perhaps it could be made clear(er) to the reader what they are?

If there are no differences, perhaps they could be filtered out?

These are different on some not visible properties (some cases are visible on packages page). For gap, there are in fact three packages, gap, gap-full, gap-minimal. For gmp, there are three different (before normalization) versions, 1:6.0.0-15.amzn2, 1:6.0.0-15.amzn2.0.1, 1:6.0.0-15.amzn2.0.2. For OpenBSD, there are differently flavored packages as well.

For most part, this is duplicate of repology/repology-rs#104, however there are additonal items which could be improved:

• display internal package names on packages page for information
• revisit generating user-visible names for nix, which may need to include suffix in gap case

Ah I see, that makes sense of course. And wow on that "language-pack-gnome" link :-)
