The following script was applied:
sed ':a;/part of MXE.$/{N;s/\n//;ba}' -i $(git grep -l 'part of MXE')
sed 's/\(part of MXE\).*\(See index.html\)/\1. \2/' -i \
$(git grep -l 'part of MXE.*See index.html')
before='This file is part of MXE. See index.html for further information.'
after='This file is part of MXE. See LICENSE.md for licensing information.'
sed "s/$before/$after/" -i $(git grep -l 'part of MXE')
Then git grep 'index.html for further information' revealed two other files.
One of them was patched manually (patch.mk). Makefile has text
"See index.html for further information" unrelated to licensing.

"The HDF-EOS2 is a software library designed built on HDF4 to support
EOS-specific data structures, namely Grid, Point, and Swath. The new
data structures are constructed from standard HDF data objects, using
EOS conventions, through the use of a software library. A key feature of
HDF-EOS files is that instrument-independent services, such as
subsetting by geolocation, can be applied to the files across a wide
variety of data products."
