[Xastir-dev] Editor header in source files

Emacs.  Tells it that when it is in C editing mode, to indent by four chars
and not use tabs, no matter what other settings the user might have in his
or her defaults.

Since I NEVER code to that standard (ick) except when working on Xastir, my
editor is set up to indent by two chars, not four.  If I don't have this line
in the file, my defaults wind up corrupting the file while I'm editing it.  And
God forbid I try to reformat the whole file (like I had to do on interface.c
and some others that had egregious indentation violations) without that line
in place.

I have no idea what header Vim uses to override default settings.  You're
on your own there.

I only add this line to files when I actually edit one, I don't add them
willy-nilly.  No harm would come from putting it in all of them.
