In org-mode, if one writes a math expression in a section (i.e. heading)
while using cdlatex, pressing tab indents the section instead of
performing a cdlatex-tab.
This fix takes care of this issue to have the wanted behavior: if in
math environment and hit tab while in section, execute cdlatex-tab.
