chomp removes $/ which is just LF, not CRLF. Yes, even on Windows. So chomp wouldn't fix appended CRLF, just appended LF. 

use Data::Dumper;
$Data::Dumper::Terse = 1;
$Data::Dumper::Useqq = 1;
print(Dumper($/));         # "\n"
$_ = "abc\x0D\x0A";
print(Dumper($_));         # "abc\r\n"
chomp;
print(Dumper($_));         # "abc\r"

But readdir doesn't append CRLF or LF to the file names it returns. Not unless you have a broken perl. 

>copy nul foo
        1 file(s) copied.

>copy nul bar
        1 file(s) copied.

>perl -e"opendir $dh, '.' or die; print readdir $dh"
...barfoo

Tested with Perl 5.6.0, 5.6.1, 5.8.0, 5.8.8 and 5.10.0.
