Remove All CVS Id Strings Possible Using a Script

Script does what is expected and tries to do it as
smartly as possible.

+ remove occurrences of two blank comment lines

next to each other after Id string line removed.

+ remove entire comment blocks which only exited to

contain CVS Ids

+ If the processing left a blank line at the top of

a file, it was removed.

1	Description: Avnet MCF5282
2	============
3	CPU: MCF5282, 59MHz
4	RAM: 16M
5	ROM: 8M
6
7	This is an evaluation board that uses the MCF5282 Coldfire CPU. It runs at about 59MHz scaled
8	from a 7.372MHz crystal and is integrated with the Avnet designed AvBus.
