"Emacs Lisp source code" ?

I've been creating some G-code in Gedit, and I've just noticed that, while most of my files saved as .ngc are listed in my folder type column as "plain text document", some are now appearing as "Emacs Lisp source code".

They seem to appear in Axis with no observable problem, and soon I shall be trying them on the mc.
However, I'd like to know where this behaviour is coming from, as I still create my files in exactly the same way as before, and always work from scratch, typing the code straight in, and saving as .ngc .

Can anyone enlighten me ?
Thanks,
John

Gedit is a graphical interface to emacs, I think. And, the emacs editor is written in Lisp.
There is no directory field that tells the type of a file, so some file browsers
and other utilities look at the first line or so of a file to determine type. I'm
guessing maybe something in your G-code initialization line looks like
lisp and causes this quirk. Maybe your fist line has parentheses in it?
(Lisp has LOADS of parens in its code.)

Thanks Jon, your deduction was spot on.
I often put a commented out text at the beginning of a file describing the contents before I have entered any code.
As I had to edit it further down, I also moved the comments down, behind my usual first line of
G17 G21 G40 G49 G54 G80 G90 G94
and saved the file with a new name. Sure enough, it was saved as a plain text file.

Respect,

John
