This is a bug in the readline/history libraries used by bash. I haven't
tracked them down as yet. I hope to get some time this week to take a look at
it. The data is saved but with extra ^M's. It appears that there is a ^M on
each line for each time the history file is written to. So when `exit' is
written it is written as `exit^M'. The next time the history is saved the
previous `exit^M' becomes `exit^M^M'. The routines must error on the ^M if
binmode isn't set in the CYGWIN variable.
I've found that if I have binmode set and remove any existing ~/.bash_history
file that the ^M's aren't written to the file. Therefore, as a workaround
until the problem can be fixed, set the binmode switch in the CYGWIN
environment variable. This is supposed to be the default and I don't have a
clue as to why specifying the switch vs not specifying the switch makes a
difference but it does.
