Yes; I see the problem there.
This is a duplicate of that bug report.

Ah, I didn't realize netrc.el had been replaced by auth-source.el.

As a simple test I tried feeding it my actual ~/.netrc — some entries
are newline delimited, and some are all-on-one-line — but it didn't
seem to find ANY of them:

    (auth-source-netrc-parse :file "~/.netrc") ⇒ nil

But if I open .netrc manually, go to point-min, and call

    (auth-source-netrc-parse-entries #'identity 999)

…it returns a correctly parsed list, handling comments & newlines between 
fields perfectly.

I'm a bit puzzled which bit of code is failing to handle newlines.
Am I missing something obvious?

(I haven't read auth.info yet because I've gotta go get it specially
due to the DFSG/GFDL dispute.)

Understood, and agreed.
