If I'd have a programming language, this would not be a problem. You're right. But I don't have one. I have a regular expression and a template and the restriction that the group 1 should contain the version number. You could say that this is too restrictive, but it covers 99% of all packages. That is why I'm asking here for a change. If there are no other considerations like backwards compatibility, sqlite-amalgamation-3.36.zip is better for a human than sqlite-amalgamation-3360000.zip.
