Redundant leading space in the result returned by 'n bin'

n/bin/n

Line 647 in 4d67e79

printf "$bin \n"

First of all thanks for a great tool!
Noticed that resulted string, returned by n bin command, contains a space at the end. In some cases like ls "$(n bin 0.12.7)" it may become crucial. Latter command will produce error ls: /usr/local/n/versions/node/0.12.7/bin/node : No such file or directory.
