I don't use proxies, so I can't test this, but looking at the code
quickly, it looks good.  (But see comments below on style.)

Do you have FSF copyright assignments for Emacs on file?

Lines should preferably not be longer than 80 characters.

Don't put closing parentheses on separate lines -- they should be on the
previous line.
