This is true in general, but not always.  Neither field splitting
nor filename generation are performed on the RHS of a simple
assignment.

        var=$this_is_fine

However, you would have to take care with something like this.

        var=$(cmd "$quote_this_one")

There is no way that the dots were changed to spaces through a mere
lack of quoting.  Something else in your code did this, and you are
misattributing it.
