bash: Retrieving Android image filenames over adb shell

Question

Here's a one-liner that is driving me nuts:

$ adb shell ls /sdcard/DCIM/Camera | grep IMG_20150630|while read f; do echo "pull /sdcard/DCIM/Camera/$f"; done
pull /sdcard/DCIM/Camera/IMG_20150630_091806.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_091817.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_091819.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_091822.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_091842.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_175231:nopm:.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_175340:nopm:.jpg
pull /sdcard/DCIM/Camera/IMG_20150630_222520.jpg

Fine. Now I want to add something after $f:

$ adb shell ls /sdcard/DCIM/Camera | grep IMG_20150630|while read f; do echo "pull /sdcard/DCIM/Camera/$f ./"; done
 ./l /sdcard/DCIM/Camera/IMG_20150630_091806.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_091817.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_091819.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_091822.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_091842.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_175231:nopm:.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_175340:nopm:.jpg
 ./l /sdcard/DCIM/Camera/IMG_20150630_222520.jpg

WTF?! The chars added after $f are actually added to the begining of every line.

There was a CR. I guess that adb returns a CRLF for every line? Weird, there's no Windows involved here.
