Done. Nevertheless Gnus should initialize the variable to nil when it
starts IMO.

The problem of undefined variables happens often.  Hm.  Does it make
sense to put an autoload marker on the variable?

What criteria do Emacs developers use to decide whether to mark a
variable to autoload?

Yes, I think so...  I'm not 100% sure, though.

I guess if it's usual to alter the variable before you load the
package, then it should be autoloayded.  I'm not sure why the user
here isn't just setting the variable instead of using `add-to-list'
and the like.

It's my fault, maybe.  I like to advise people to use add-to-list for
lists, and mail-sources is a list.  The rationale is that people might
be using the default value, and then just setting it won't work
right: it will remove the default mail source.

Also, I think it's more consistent to teach them to use add-to-list
for lists (and add-hook for hooks) so that they don't get confused
too much.

Yes, that's true.
