Revert "Fixed minor logic inverson in MultiLine/PPI.pm"

This reverts commit d8153bec650b92d2cd68449a148c393c51e877e9.
The fix made it possible to continue q{} constructs across
lines but, it also allowed "q\n" to continue as well which
is not valid.  Reverting until further investigation can be
made.
