Improve line wrap removal heuristics.
* tex-buf.el (TeX-format-filter): Remove linebreaks at columns 79
and also column 80. Also remove linebreaks preceded by a period
that are followed by a word character to remove linebreaks in file
names that are wrapped just after the period starting the file
name extension.
