Additional carriage return added by cygwin commands to DOS text files

However a non-transparent hack is to use first a text filter then pipe 
its output to the original command. The filter opens the file in 
textmode so it gets rid of the CR. Then, as expected, no CR are present 
in the pipe. Then normal CRs are added in the resulting file when it is 
written on disk.
The "more" command is a good choice for such a filter, because its pager 
functionality is disabled when it writes to a pipe, so it acts as a 
simple repeater in textmode: exactly what we need.
$ more test1 |grep -U -E 'a|b' > test2
$ xxd test2
0000000: 6161 610d 0a62 6262 0d0a aaa..bbb..
The result is correct.
