I do not think we updated Coding Guidelines to allow // comments.

Since this was a tutorial I thought this was helpful, anyways I will
remove the comments, because I get that this would be bad practice for
newbies.

I meant that I think our guidelines frowns upon

	#include "foo.h" // for bar()

I didn't mean a comment is necessarily bad.  IOW,

	#include "foo.h" /* for bar() */

may be OK.

But real programs will evolve and API elements that are used from a
header file will change over time, so it may not be a good idea to
single out a function like that in the comment.  It would be much
better to explain _why_ each change is made in the text that
precedes the sample code.  E.g.

    Add `#include "config.h"` because you want to use X and Y,
    and `#include "repository.h"` because you want to use Z.

    Then, add the following bits to the function body:

     ----
    #include "builtin.h"
    #include "gettext.h"
    #include "config.h"
    #include "repository.h"
    ...
    int cmd_psuh(int argc, const char **argv, const char *prefix, struct repository *repo)
    {
        const char *cfg_name;

        printf(Q_("Your args (there is %d):\n",
