Comment 2 for bug 1914625

I don't have anything against the idea (there seems to be a surprisingly large preference for vim in the Eg community) but there are 2 problems as it's implemented currently.

First, vi/m modelines are only looked for in the first or last few lines. (I've seen reference to 5 lines but haven't found a definitive answer for modern vim's), so as-written this would stop the vim modeline from being working. Depending on how many lines into a file emacs will look for local variables they could be placed above the vim modeline or worst case, vim could have the top and emacs the bottom, or vice-versa.

Additionally, while I agree that consistent tab/space-ification for fm_IDL.xml is a good goal, it should be a separate commit from any other changes.
