Yes you do...

... if you read character by character, use the function 
Text_IO.End_Of_Line  to detect the end of an input line. This works the 
same way in all systems, whatever line termination character (sequence), 
if any, is used. Follow with Skip_Line to go to the start of the next line.

To return to the subject: I too often use 'Image for normal output, not 
just for debugging. And I find the extra blank annoying. But it is a 
very small annoyance, considering what else life offers :-)
