[release-branch.go1.14] go/doc: fix detection of whole file examples
After CL 211357 (commit
499dc1c),
hasTests and numDecl were not updated properly for function
declarations with parameters, which affected the whole file
example detection logic. This caused examples like
package foo_test
func Foo(x int) {
}
func Example() {
fmt.Println("Hello, world!")
// Output: Hello, world!
}
to not be detected as whole file ones.
Fixes #38418.
For #38409.
