    * doc/extend.texi (__builtin_object_size):
    Use @pxref instead of @xref inside parenthesis.
    (__builtin_has_attribute): Add missing comma after @xref.
    (__builtin_object_size): Ditto.
    * doc/md.texi (cond_*{mode}): Use @samp instead of @var around op1[i].
    * fortran/invoke.texi (-ffpe-trap): Use @var for every item
    in the list.

Bootstrapped on x86-64-linux-gnu, committed to mainline SVN as obvious.

Uros.
