etc etc

Heres a small snippet of directories.

$ pwd

$ ls
abbrev.elc             foldout.elc           pcmpl-gnu.elc
abbrev.el.gz           foldout.el.gz         pcmpl-gnu.el.gz
align.elc              follow.elc            pcmpl-linux.elc
align.el.gz            follow.el.gz          pcmpl-linux.el.gz
allout.elc             font-core.elc         pcmpl-rpm.elc
allout.el.gz           font-core.el.gz       pcmpl-rpm.el.gz
allout-widgets.elc     font-lock.elc         pcmpl-unix.elc
allout-widgets.el.gz   font-lock.el.gz       pcmpl-unix.el.gz

As you can see all files are elc or gzipped el.

Oh emacs opens gzipped files alright, so I guess auto-compression is working.
