[O] Warning about section named "Footnotes"

[Arni Magnusson]

Dear Org maintainers,

I was using Org to write a software manual with a structure along the 
lines of:


* Equations

How to write equations in software FOO.

* Footnotes

How to write footnotes in software FOO.

* Images

How to insert images in software FOO.


When I exported the document (to LaTeX and HTML), I was puzzled to find 
that one of the sections was not exported at all...

After investigating the problem for a while, I realized that if a section 
is named "Footnotes" the default behavior of Org is to ignore it silently.

My solution was to set `org-footnote-section' to nil.


I think it would help Org users if:

1. Org export (to LaTeX, HTML, etc.) emits an error or a prominent warning
   when it ignores an entire section like this.

2. The manual would warn the user about this behavior with a prominent
   warning.


Thanks for maintaining Org-mode. I'm finding it quite convenient for a 
variety of tasks.
