It's definitely not a bug. Quoting the expansion inhibits word splitting. Y=
our loop iterates once over a single word. Said word is conveyed to echo as=
 a single argument. In this case, said argument is printed by echo, with th=
e addition of a newline character. If your ultimate intent is to store an a=
rbitrary list of strings in a variable prior to iterating over them, you sh=
ould use an array variable instead. As such, this would be a topic better s=
uited to the help-bash list.
