  Log Message:
  -----------
  [flang][runtime] Don't do partial data transfer on short character read with ADVANCE='NO', PAD='NO'

When a non-advancing formatted READ can't completely fill a CHARACTER
input item with data, and PAD='NO', don't modify the variable at all.
This matters when the error is recoverable.
