1. get rid of grammar mistake
2. refer to COPYING-PLAIn correctly as the filename
3. be more explicit on "shipping source" due to ambiguity (this makes it what
it was intended to be and that is GPL compatible).
this does not modify the LGPL libs... or GPL apps etc. - only those using the
original COPYING from e. author and dates at the top remain the same.
