# golang.org/issue/34055
# Starting in Go 1.25, go-import meta tag support an optional subdirectory paramater.
# The corresponding go-import meta tag is specified as
# <meta name="go-import" content="vcs-test.golang.org/go/gitreposubdir git https://vcs-test.golang.org/git/gitreposubdir foo/subdir">
# and contains the module in vcs-test.golang.org/git/gitreposubdir/foo/subdir.
# See testdata/vcstest/go/gitreposubdir.txt and testdata/vcstest/git/gitreposubdir.txt
