Dear all,

I have, until now, used a macro

  #+macro title The title of the document

to be subsequently used in the actual #+title line, as in

  #+title: @@latex:...@@ {{{title}}} @@latex:...@@

(LaTeX details not important, I think.)

but this now leads to a recursive evaluation of the line when exporting,
causing an infinite loop.

Changing the name of the macro to something else avoids the issue.  I'm
not entirely sure why a macro expansion of the #+title line would be
recursive but there you are!
