I think its due to the fact that interpreters like 'sed', 'Perl' ignores 'CR' (chariage return) characters on windoze..........
Don't know about "sed" on Windows, but that would be highly unusual for Perl on Windows:

Code:
C:\>
C:\>REM create a file that has \x0D characters at multiple places
C:\>perl -le "print \"\x0D The quick \x0D brown fox jumps \x0D over the lazy dog.\x0D\"" >f0
C:\>
C:\>REM check the file contents
C:\>vis <f0
\015 The quick \015 brown fox jumps \015 over the lazy dog.\015
C:\>
C:\>REM do an inline replace of all \x0D characters to \x0D\x0A
C:\>perl -i.bak -pe "s/(\x0D)/$1\x0A/g" f0
C:\>
C:\>REM now check the file contents again
C:\>vis <f0
\015
 The quick \015
 brown fox jumps \015
 over the lazy dog.\015

C:\>
C:\>REM print file using the DOS "type" command
C:\>type f0
 The quick
 brown fox jumps
 over the lazy dog.

C:\>
C:\>

The perl interpreter used in the example above is from the ActiveState Perl installed using MSI.

"vis" is just a small C program that makes non-printable characters visible in octal code.

wordwrap - Wraps a string to a given number of characters

SYNOPSIS
string wordwrap (string $str, [int $width = 75], [string $break = "0], [bool $cut = false]) DESCRIPTION
Wraps a string to a given number of characters using a string break character. PARAMETERS
o $str - The input string. o $width - The number of characters at which the string will be wrapped. o $break - The line is broken using the optional $break parameter. o $cut - If the $cut is set to TRUE, the string is always wrapped at or before the specified $width. So if you have a word that is larger than the given width, it is broken apart. (See second example). When FALSE the function does not split the word even if the $width is smaller than the word width. RETURN VALUES
Returns the given string wrapped at the specified length. EXAMPLES
Example #1 wordwrap(3) example <?php $text = "The quick brown fox jumped over the lazy dog."; $newtext = wordwrap($text, 20, "<br /> "); echo $newtext; ?> The above example will output: The quick brown fox<br /> jumped over the lazy<br /> dog. Example #2 wordwrap(3) example <?php $text = "A very long woooooooooooord."; $newtext = wordwrap($text, 8, " ", true); echo "$newtext "; ?> The above example will output: A very long wooooooo ooooord. Example #3 wordwrap(3) example <?php $text = "A very long woooooooooooooooooord. and something"; $newtext = wordwrap($text, 8, " ", false); echo "$newtext "; ?> The above example will output: A very long woooooooooooooooooord. and something SEE ALSO
