Hmm. The parser I implemented only does single-line parsing, and I
misunderstood the format to be single-line (partly because I have never
seen anyone using the multi-line format you show).  Looking at
Net::Netrc more carefully, it seems that the "machine" token is what
defines an entry, so a new entry starts with a new line that contains a
"machine" token.  Is that acceptable and does it match your
understanding of the format?  It matches Net::Netrc, at least.

I'll add this change to PATCHv4 with the assumption you agree.

OK, I'll review these for PATCHv4 (also see below).  Thanks.

After thinking about it, I agree with Peff multiple sources make sense
and will simplify the code flow (especially the default case, which
won't need to be handled separately).  And the functionality doesn't
have to be confusing with the right debugging messages.  So I'll add
them in PATCHv4.

The debugging messages will be fewer and simpler with this approach,
which makes it feel like the right track :)
