Fix bug in ml_count.c [from: a_m0d]

  - "This patch fixes a bug with string handling in ml_count.c.
    The bug occurs with escaped string characters - when a file
    contains a quoted string character ('\"') then ml_count will
    crash with the message
      ml_count ERROR - terminated in string in
      ~/workspace/sloccount/trunk/../../basic//src/lexer.mll
    This patch fixes this by ensuring that escaped quotation marks
    do not mark the start of a string.
