Sorry, I lost this email for a while when I was switching machines.

Interesting. I have never seen a file like this in practice, but I have
not used Red Hat in a long time. Thanks for bringing this to my
attention.

Recently it's come to my attention that there's already a function that
does this in tramp: tramp-parse-hosts will return a list of user/host
pairs, though on my machine it also returns some key signatures. (I
imagine it could use some debugging as well.)

Clearly this shows some redundancy that should be removed. But I'm not
sure what the best way to go about this is. I don't think pcomplete
should require tramp, nor vice-versa. Perhaps it should be spun out into
a third file that the other two require? I don't feel I have a great
grasp on how files are organized within Emacs.

Thoughts?
