The change to revert \[ to $$ is trivial. Here it is:

Indeed. See above. You also need to download
$ wget http://zwiki.newsynthesis.org/plugins/mathaction/useproto.h
Then just compile the file:
$ gcc texbreak.c -o texbreak
Use it like this:
[EMAIL PROTECTED]:~$ cat test.tex
Here is some stuff
$$
{{1 \over {11}} \ {x \sp {11}}}+{x \sp {10}}+{5 \ {x \sp 9}}+{{15} \ {x
\sp 8}}+{{30} \ {x \sp 7}}+{{42} \ {x \sp 6}}+{{42} \ {x \sp 5}}+{{30} \
{x \sp 4}}+{{15} \ {x \sp 3}}+{5 \ {x \sp 2}}+x
\leqno(5)
$$
and this is the end.
