I do not use Maildir myself but people who do not know how Maildir look
like (including myself) would be left wondering why there is even no error
message when giving a random directory full of format-patch output to am.

I am wondering if something like this would be helpful...

I don't use maildirs with git, but I have worked with them in the past,
and I think your patch is definitely an improvement.

However, I wonder if we could go one step further and just DWYM: if a
directory has "cur" or "new", treat it like a maildir (IOW, look in
there for patches), but otherwise treat it like a directory of
format-patch output.
