Maybe Hans can fix this extra spacing problem. I joined the pdf output I get with my minimal sample. The font problem occurs on line 3 where the last parenthesis is smaller than expected.

Yes but in my cases I do want a mathematic display and not an chemicalformula
one because I want to express a mathematical formula where chemical formulas
are indexes. As an example, considere the calculation of the molecular weight:
M(C6H12O6) = 6 M(C) + 12 M(H) + 6 M(O)

In fact, it's an habit I made when I used to put chemical formulas in
subscript like in: m_{H20} = ... With \math{m_{\chemical{H_2O}}}, H2O was
typed in normal font whereas with \math{m_{\text{\chemical{H_2O}}}}, it was
typed in subscript font as expected. Did not test if it's still the case.

So I will wait for the new rewritten macros.
Thanks again.
