Auto merge of #12659 - Eh2406:Prerelease_candidates, r=epage
Prerelease candidates error message ### What does this PR try to resolve? Error messages reporting on versions that do not match the request incorrectly ignore pre-release versions. This is because the version requirement `"*"` cannot match prerelease versions. #12315 ### How should we test and review this PR? Sorry for the large amount of white space changes, fmt got to fmt. 🤷♂️ The process was: - Revise commit from #12316 (thanks to `@loloicci)` that change the requirement from `"*"` to `Any` - Move the handling of our special "did you mean to specify a pre-release" code and update tests - some small re-factoring ### Additional information The old "did you mean to specify a pre-release" #7191 check only occurred when version requirement does not match any versions and you depended on a package that did not have any non-prerelease versions. Making it rarely useful. The new one will appear any time your version requirement does not match any versions and the package does have pre-release versions. Which may be too common. I'm open to suggestions for better heuristic. It's also not clear that the new message make sense in the case of patched versions.
