      Bug#12589167 60901: 5.6.2 CLIENT TRUNCATES LINES AT
                   255 CHARS/MULTILINE QUERIES DONT WORK
                   ON WINDOWS
      
      The synopsis of the bug does not outline the real
      problem. The actual problem being the copy/paste,
      i.e. whenever a multi-lined string is copied leaving
      the trailing line-separator characters "CRLF" of the
      last line, the first character of the last line
      always gets altered to 'm', and that is the reason
      behind this bug.
      
      Fixed by changing the way lines are read from the
      console buffer (initially done as part of WL#5331).
      Now, the entire line will be read in a single go
      instead of character-by-character reading.

        Changed the way lines are read from the console input
        buffer. Now, (post-patch) ReadConsoleW() function will
        wait (block) for the entire line to be entered, and then
        will copy the entire line to 'u16buf' buffer.
