Bug#935968: texlive-latex-extra: Font U/esint/m/n/10.95=esint10 at 10.95pt not loadable: Metric (TFM) file not found

[Karl Berry <karl@freefriends.org>]

            esint10.mf
    is empty, besides comments and a lone
            \endinput

    Is this on purpose?

No, I just didn't notice. In the 2019/07/19 update of esint, esint10.mf
is supposed to be generated from esint.dtx, while only that stub file in
fact shows up. I am not sure. Running the .ins shows:

Processing file esint.dtx (muffle) -> esint10.mf)

And I wonder if that "muffle" should be "mffile", as the dtx has:
%<*mffile>
% Computer Modern Math Extension 10 point
..

I can't dig further right now. Eddie, help, please?

By the way, once the real esint10.mf is there again, the tfm will be
made automatically.

Also, the real esint10.mf is available in any previous release.

Thanks,
Karl
