input.c, try to work around microsofts broken _read()

concerning the visual sudio variant of the "console" build.

Their _read() returns 0 when a linfeed is read.
Ironically the linefeed seems to be stored into the buffer nontheless.

Because the filehandle is in linebuffered mode anyway,
  (the read won't return up until the terminating newline is entered)
we can just as well use getc(), which doesn't seem to suffer
  from the same problem in their implementation.
