Make the s-record output routine work like the raw and intel hex 

output routines (don't optimize away 0xff data before and after non
0xff data).  Also, fix a bug where the data contents sometimes weren't
written out completely.

Initial bug reported by Tom Harris <TomH@optiscan.com>.  Fixes
provided by Alexey V.Levdikov <tsar@kemford.com>.
