Say we make a one line text file called "a" that contains
    w  CR  LF

and then give the command:
    grep -v "<" < a > b

File "b" will consist of:
    w  LF

In effect, grep has removed the CR. The bug was first found in a 66 line
.bat file where it was a bit of a nuisance.

For what it's worth grep.exe on my system is 80412 bytes and is dated 23
Jan 2014.

Best wishes,
Nick Hawthorn
