macros.itexi

[Graham Percival]

I've simplified the english macros.itexi.  While I was adding @rlearning 
macros to the translated macros, I noticed that the de and es use
@internalsref
for things like @user, @program, etc.  I followed the same style, but 
surely those should be @ref{} instead?


Regardless, I think it would be worth completely replacing the 
translated macros.itexi files with a newly-translated version of the 
file from the main docs -- it should be much easier to maintain the new one.

This is a GDP-only change, of course.

Cheers,
