I don't have a strong opinion on this one.

It remaps the key binding.  The culprit of course is that, say, if you
opened a LaTeX file, did some grepping and then want to use `M-g n'
for navigating the grep buffer this won't work because
`TeX-next-error' is called directly.  There is no searching for
`next-error'-capable buffers.

Here is the patch which should make things clearer:
