ChangeLog file issues

[Werner LEMBERG]

Folks,


for further commits, entries in the `ChangeLog` file are no longer
necessary.  Instead, we will auto-generate this file, as is done by
other GNU projects like 'Emacs' or 'coreutils'.

To make that work, I ask to format git commit messages in the same
style that has been used in the last years!  We will soon prepare a
template to help people write such messages, documenting the format.
