On minGW host, history file are open in text mode, that's imply windows 
specific
carriage return to be inserted ( \n -> \r\n conversion performed) and 
prevents windows history file to be compliant with linux one's.
When using current history file for windows, "^M" appears at each end of 
line.

This patch fixes this problem.
