Strange. Did you perhaps start with a file that you got from elsewhere and 
modified that? Gedit may have left the CRs untouched then.

cat -v filename

is one option. CR (or "\r", or chr(13), or carriage return) shows up as ^M.
The ^ means "subtract 64 from the byte value", e. g. 

^M = chr(ord("M")-64) = chr(77-64) = chr(13)
