The generated file warning should appear even if the DO NOT EDIT comment is not on the first line

[kennytm]

In #1425 (which fixes #1295), VSCode will show a warning if the first line of the code contains the comment matching ^// Code generated .* DO NOT EDIT\.$. However, as specified in https://golang.org/pkg/cmd/go/internal/generate/, this comment can appear anywhere, so it is wrong to just detect the first line.

To convey to humans and machine tools that code is generated, generated source should have a line that matches the following regular expression (in Go syntax):

^// Code generated .* DO NOT EDIT\.$

The line may appear anywhere in the file, but is typically placed near the beginning so it is easy to find.

#1425 was a best effort made under the circumstances to provide a warning.
In order to support the DO NOT EDIT comment on any line, we will have to parse the entire file which I would prefer not to do as it can get expensive on very large files.

Now that we have support for language servers, they are in a better state to handle parsed file contents.

@stamblerre Is this something you would consider gopls to do?

[stamblerre]

Yes, gopls could do this and send it as a diagnostic.

Thanks @stamblerre
