WONTFIX - you can avoid long lines by using multiple AllowUsers directives as
each gets added to the list. E.g. your example could be written:

AllowUsers user1 at host1.somewhere.com user1 at host2.somewhere.com
AllowUsers user2 at host1.somewhere.com user2 at host3.somewhere.com

Hmmm, I've created a few ProxyCommand pipes that wouldn't fit into 80 
characters, and it wouldn't really make sense to have multiple ProxyCommand 
options. (are they piped together?  &&'d?  should I need to create a
file and
sh -c it?)

\ as a line extension mechanism has a decent amount of precedent -- I think 
it's been around since bourne shell -- and might make some configuration
files
easier to read.  The main cost I see is that, as far as I know, there's not
a
mode to make grep aware of the backslash.  That would mean

$ grep AllowUsers /etc/sshd/sshd_config

would return only the first line of users allowed.

So:  Is it better to have something more usable and more standard for users to 
enter configurations into, or is it better to be compatible with per-line 
parsing systems?

I'm not really sure.  We've already sacrificed line independence -- a
group of
options can be encapsulated by a pattern match; the above grep would match all 
patterns equally.  Damien -- what's your reasoning for disliking \ notation,
out of curiosity?

It adds complexity where it is not required. OpenSSH has a simple line-at-a-time
config parser, it doesn't need to be more complicated.
