Do not allow a pseudo-version derived from a canonical tag to refer to
the same revision as the tag itself. It's unnecessary (because
canonical tags already have a total ordering) and confusing (the
pseudo-version appears to come after the tag, but actually refers to
the exact same revision).

Previously, most operations involving pseudo-versions allowed any
arbitrary combination of version string and date, and would resolve to
the underlying revision (typically a Git commit hash) as long as that
revision existed.
There are a number of problems with that approach:
• The pseudo-version participates in minimal version selection. If its
version prefix is inaccurate, the pseudo-version may appear to have
higher precedence that the releases that follow it, effectively
“pinning” the module to that commit. For release tags, module
authors are the ones who make the decision about release tagging;
they should also have control over the pseudo-version precedence
within their module.
• The commit date within the pseudo-version provides a total order
among pseudo-versions. If it is not accurate, the pseudo-version
will sort into the wrong place relative to other commits with the
same version prefix.
To address those problems, this change restricts the pseudo-versions
that the 'go' command accepts, rendering some previously
accepted-but-not-canonical versions invalid. A pseudo-version is now
valid only if all of:
1. The tag from which the pseudo-version derives points to the named
revision or one of its ancestors as reported by the underlying VCS
tool, or the pseudo-version is not derived from any tag (that is,
has a "vX.0.0-" prefix before the date string and uses the lowest
major version appropriate to the module path).
2. The date string within the pseudo-version matches the UTC timestamp
of the revision as reported by the underlying VCS tool.
3. The short name of the revision within the pseudo-version (such as a
Git hash prefix) is the same as the short name reported by the
underlying cmd/go/internal/modfetch/codehost.Repo. Specifically, if
the short name is a SHA-1 prefix, it must use the same number of
hex digits (12) as codehost.ShortenSHA1.
4. The pseudo-version includes a '+incompatible' suffix only if it is
needed for the corresponding major version, and only if the
underlying module does not have a go.mod file.
We believe that all releases of the 'go' tool have generated
pseudo-versions that meet these constraints. However, a few
pseudo-versions edited by hand or generated by third-party tools do
not. If we discover invalid-but-benign pseudo-versions in widely-used
existing dependencies, we may choose to add a whitelist for those
specific path/version combinations.
―
To work around invalid dependencies in leaf modules, users may add a
'replace' directive from the invalid version to its valid equivalent.
Note that the go command's go.mod parser automatically resolves commit
hashes found in 'replace' directives to the appropriate
pseudo-versions, so in most cases one can write something like:
replace github.com/docker/docker v1.14.0-0.20190319215453-e7b5f7dbe98c => github.com/docker/docker e7b5f7dbe98c
and then run any 'go' command (such as 'go list' or 'go mod tidy') to
resolve it to an appropriate pseudo-version. Note that the invalid
version will still be used in minimal version selection, so this use
of 'replace' directives is an incomplete workaround.
―
One of the common use cases for higher-than-tagged pseudo-versions is
for projects that do parallel development on release branches. For
example, if a project cuts a 'v1.2' release branch at v1.2.0, they may
want future commits on the main branch to show up as pre-releases for
v1.3.0 rather than for v1.2.1 — especially if v1.2.1 is already tagged
on the release branch. (On the other hand, a backport of a patch to
the v1.2 branch should not show up as a pre-release for v1.3.0.)
To address this use-case, module authors can make use of our existing
support for pseudo-versions derived from pre-release tags: if the
author adds an explicit pre-release tag (such as 'v1.3.0-devel') to
the first commit after the branch, then the pseudo-versions for that
commit and its descendents will be derived from that tag and will sort
appropriately in version selection.
