Try the following. It changes the generic command for section headings
such that a dot is printed after the section number.
Use it as a documentstyle, or enclose it in "\makeatletter" and "\makeatother".

% Change \@sect from latex.tex.
% A dot will be printed after the counter in the section heading.
% The toc - and aux entries will not be affected.
