The iopipe to range-ify.
An input range whose elements are lines of text from the input iopipe, with or without delimiters as specified by the KeepDelimiter boolean.
Convenience wrapper for byDelimRange that uses the newline character '\n' as the delimiter. Equivalent to `byDelimRange!(KeepDelimiter)(c, '\n');
