Incorrect version formatting for SBCL in search results

[kisp]

First of all, thank you for this incredibly useful tool! It’s been a great resource.

I noticed a potential issue when searching for SBCL on your site. For instance, searching for sbcl at the following link:
https://lazamar.co.uk/nix-versions/?channel=nixpkgs-unstable&package=sbcl

returns some rows with version numbers like this:

sbcl   3bmd-20230618-git   67b4bf1df4ae54d6866d78ccbd1ac7e8a8db8b73   2024-06-13

The 3bmd-20230618-git does not represent a valid SBCL version (e.g., versions like 2.4.4 are expected). This makes the version data less intuitive and potentially misleading.

For comparison, when searching for other Lisp implementations such as CLISP or CCL:

• CLISP Results
• CCL Results

the table appears "clean" and shows proper version formatting.

Could this be investigated and possibly improved for SBCL?

Thanks again for your fantastic work!

I'm glad you found it useful.
I'm afraid there isn't much that can be done on my side. I just take the version field from the packages available in specific revisions.

I see that these weird version numbers only appear in revisions since 06/2024 and that there are lots of them for each revision. There are also sensible-looking versions in those revisions like 2.4.4, 2.4.5 and 2.4.6.

Maybe @Uthar, who has been working on the LISP files will know more about it.
