A string might never be printed or read by a human outside of the code it resides in. In this case it seems perfectly reasonable to ask that it be possible to format the string nicely in the code and disregard how it would actually be printed.

The most common reason is that the code is maintained by a (non-human) developer, who wants to be able to see and update the code in a readable form, but that represents a single line that will automatically wrapped by, for example, a UITextView for (human) consumption.
