I've explained the situation in the auth.texi manual with this commit to
gnus.git, which will be synchronized into Emacs as well:

commit 01c75b7c8e4ecbdaea6dda97b113a76c60458620

    * auth.texi (Help for users): Explain quoting rules better.

Background: the original netrc.el parser just used the Lisp reader. But
that reader doesn't support single-quoted strings, which is the standard
netrc format, so I modified the parser accordingly in gnus.git:

commit 1474b920b7471e4bdb4f983b98fb767d61f8037b
Author: Ted Zlatanov <tzz <at> lifelogs.com>

    auth-source netrc backend: Support single-quoted strings, multiline entries.

I've never seen passwords or other tokens with both single and double
quotes, so IMO the current parser in `auth-source-netrc-parse-one' is
sufficient.  But I'm happy to take patches or demands for it to support
some other style.  Marking this bug as done, in any case.

Ted
