Hi there, I think this is a bug

mkdir empty_foler
cd empty_foler
touch a
echo "abc" | tr [:blank:] +  # you will get “+bc” as output, instead of “abc”
touch b
echo "abc" | tr [:blank:]  # you will get “bbc” as output, instead of “abc”

My system info:
CentOS release 6.7 (Final)
linux kernel version 2.6.32-573.el6.x86_64

$ tr --version
tr (GNU coreutils) 8.4
