No reason than for preference. This function had (accidentally) unwritten post-condition that `Result` would have file contents in it upon return. But since at least one Replacement is required to get the file name, this function would be unable to even put unmodified data in `Result`. Whether the function is left as is or just returns an empty string in the case of no replacements, some caller still needs to worry about there being no replacements.
