This reverts commit f735584514.
These header changes introduce unacceptable errors:
1. The changes alter the width of the initial block comment. That will cause nxstyle failures on most of the files.
2. The third line of the header is an (optional) short description of content of the the file. This change erroneously removes that line.
Automated header file changes can screw up a lot of files, very quickly.
