bash read oddity

["Jamin W. Collins" <jcollins@asgardsrealm.net>]

Got a strange situation happening on a friends Debian box.  I found the
problem by debugging his ALSA startup problems.  Turns out that he's
getting some extra character added to the output of "read" command.

The following commands replicate this:
   $ set -x
   $ awk '/^((alias)|(probe)) +snd-card-[0-9]/ {print $3}' \
      /etc/modules.conf | ( while read -e line; do echo $line; done; )

on my friend's system this results in:

   + awk '/^((alias)|(probe)) +snd-card-[0-9]/ {print $3}' /etc/modules.conf
   + read line
   + echo $'snd-emu10k1\r'
   snd-emu10k1
   + read line

on my system this results in:

   + awk '/^((alias)|(probe)) +snd-card-[0-9]/ {print $3}' /etc/modules.conf
   + read -e line
   + echo snd-ymfpci
   snd-ymfpci
   + read -e line

Both systems are running the same versions of bash and libc6.  Any
ideas?
