[OS X Emacs] QuickLook

[Tom Van Vleck]

This is only sort of an Aquamacs question.
For over 5 years i have created files with the name suffix ".e" meaning "open with emacs."
On OS X I have told the finder to open such files with Aquamacs when double clicked.
Did the same for ".txt" files.
Works fine.

When I view a Finder window and highlight a .txt file and hit space, a preview comes up,
and it has "Open with Aquamacs" in a button in the header.
If I do the same with a ".e" file, I get a popup window with the "Open with Aquamacs" and a big-size icon preview, name, size, and date modified.
How can I convince the Finder to open a QuickLook preview of a ".e" file just like it does a ".txt" file?
