Errors after updating to latest revision on Windows 7

[Nelson H. F. Beebe]

Cesar Romani reports that dehypht-x-2019-04-04.tex is not found
by fmtutil-user in his TeX Live 2020 installation.

I updated my 2020 and 2021 trees just this morning, and regenerated
all of the *.fmt files without error.  A check of the file trees
for older TeX Live releases finds dehypht-x-2019-04-04.tex in the
2019 tree, but not in later trees.

This could arise, perhaps, if there is a mixture of 2019 and 2020 files
in the same tree.

In my 2019 tree, the file is in texmf-dist/tex/generic/dehyph-exptl/.
