Warn me when the equation number is pushed to the next line
Is it possible to let amsmath warn me when the equation is too long and pushes the number to the next line?
I expect either it prints Equation (1) too long to console or it makes the (1) part red.
documentclass[twocolumn]{article}
usepackage{amsmath}
begin{document}
begin{equation}
A+B+C+D+R+F+G+H+I+J+L+M+N+O+P
end{equation}

I don't want to say it is impossible but it's definitely a hard problem, because amsmath relies on the eqno primitive to do this work for the equation environment.
hsize=8cm
$$A+B+C+D+R+F+G+H+I+J+L+M+N+O+Peqno(1)$$
bye
So the only way I see is to override the eqno primitive and measure the penalties to see whether the number will be flushed to the next line.
For the align family of environments it is a little easier because tag shifting is handled by macros, which you simply hook your custom error or warning into

Can we assume
align gives the same result as equation does and throw things into align and test it? Or, test the height of vbox with and without eqno?– Symbol 1
