[Groff] recent changes not in ChangeLog

[Werner LEMBERG]

Dear recent committers,


please try to update the ChangeLog file!  While many small editorial
fixes in man pages don't deserve an entry, addition of new files do
(e.g., file `letter.mm').  Similarly, changes to code – this includes
non-comment lines in macro files (e.g., `hdtbl.tmac-u' or `m.tmac') or
infrastructure files (e.g., `mm.am') – should also be tracked.

Note also that some contributed packages like `mm' have a separate
ChangeLog file; some changes have been incorrectly added to the master
ChangeLog file already.

Finally, I'm not sure that a copyright line like

  Copyright \[co] 1989\[en]2014 Free Software Foundation, Inc.

in a source code file is legal.  I think it should rather be

  Copyright (c) 1989-2014 Free Software Foundation, Inc.

If you are going to print the copyright notice in a manpage (or
whatever), then the first version can be used *additionally*.
