I tried finding where in the documentation there are instructions on sending
a bug report to the mailing list, but didn't see anything (otherwise, I'd
add some info on '--diagnose' there). Maybe Emily would know?

If instructions like that don't exist, I'll update the command documentation
here to clarify that '--diagnose' generates an attachment that includes more
complete repository information to aid in debugging.

I like the simplicity of this, but I'd imagine that a user would want to
generate diagnostics *with* a report more often than without one. The cases
I can think of for "standalone diagnostics" are: internally in 'scalar
diagnose', someone requesting more info after an initial bug report, or a
user looking into something on their own.

Maybe I could replace '--no-report' with '--diagnostics-only'? Then the
three modes of use would be:

- 'git bugreport': report only (most common usage)
- 'git bugreport --diagnose': report + diagnostics
- 'git bugreport --diagnostics-only': diagnostics only (least common usage)

It would eliminate the need for "nothing to do" while making it (I think?)
clearer to a user why you would want to use any of these options.
