There is no way to add an end marker without using a new line (or use 
'\r' which is really unacceptable, and more justifiably so).  Since we 
are settling in on having 50 (?probably want to use a #define) dots 
unless there are fewer than 50 units to be written, I suppose we can 
live without a end marker.  Sigh, the end marker was the fun part.

I also contend that it was a useful part even if you /know/ that there 
will be 50 dots because the human eye cannot count dots at a glance.

Illustration:

Tell me at a glance how close this is to completion[1]:
Writing to Flash..............................

Now tell me here:
Writing to Flash
                                                   v
..............................

With an added parameter to the flash write routine (which would serve 
double duty to suppress the progress dots), I can condense the above 
into two lines.  This is still 100% more lines than Wolfgang demands, 
but I think it has sufficient value to pay its freight.

Writing to Flash                                  v
