Subject: emacs: fix read error when opening helpful buffers

helpful tries to find sources, which could be gzipped.  In this case,
there needs to be a `file-name-handler` to decompress the file.  I
wasn't correctly saving the initial value of `file-name-handler-alist`
in my configuration (the default includes a gzip handler).
