With sys-apps/texinfo-5.1 installed, sci-mathematics/octave-3.6.4 produces errors about misplaced braces in the src_install phase.


Reproducible: Always

Steps to Reproduce:
1. emerge '=sys-apps/texinfo-5.1'
2. emerge '=sci-mathematics/octave-3.6.4'

Actual Results:

../../../doc/liboctave/liboctave.texi:83: misplaced }
../../../doc/liboctave/liboctave.texi:84: misplaced {

../../../doc/liboctave/liboctave.texi:85: misplaced {
../../../doc/liboctave/liboctave.texi:85: misplaced }
../../../doc/liboctave/liboctave.texi:86: misplaced {

make[1]: *** [../../../doc/liboctave/liboctave.info] Error 1
make[1]: Leaving directory `/home/amod/workspace/octave/build/doc/liboctave'


Expected Results:  
The package should merge smoothly.


Excerpt from <https://lists.gnu.org/archive/html/info-gnu/2013-03/msg00007.html>:

> . @-commands are now recognized in raw format blocks.  Therefore, for

Following is a patch (seems quite short, so not uploading it as an attachment).
I'm not sure whether this goes well with older texinfo versions, and you might need to make a test.
