* Call flush for endl if ENDL_CALLS_FLUSH is non-zero
*
* The standard for iostreams is to call flush. This is very costly for
* SdFat. Each call to flush causes 2048 bytes of I/O to the SD.
*
* SdFat has a single 512 byte buffer for I/O so it must write the current
* data block to the SD, read the directory block from the SD, update the
* directory entry, write the directory block to the SD and read the data
* block back into the buffer.
*
* The SD flash memory controller is not designed for this many rewrites
* so performance may be reduced by more than a factor of 100.
*
* If ENDL_CALLS_FLUSH is zero, you must call flush and/or close to force
* all data to be written to the SD.
