Fortran news.texi broken on trunk

[Richard Earnshaw]

Trunk updated from CVS this morning dies while trying to run makeinfo on 
f/news.texi:

  /home/rearnsha/gnu/egcs/arm-aout/texinfo/makeinfo/makeinfo  
-I../../../../gnusrc/egcs-cross/gcc/f -o f/g77.info 
../../../../gnusrc/egcs-cross/gcc/f/g77.texi; \
else true; fi

`ifclear', but saw `itemize'.

makeinfo: Removing output file `f/g77.info' due to errors; use --force to 
preserve.
Making info file `f/g77.info' from `../../../../gnusrc/egcs-cross/gcc/f/g77

gnumake[1]: *** [f/g77.info] Error 2

The nesting of the @end statements is clearly wrong on examination.
