You can always use "\n", and if you use the /m modifier:

 /regexp/m

then the wildcard dot will match \n's.

So, given a two-line string:
   1182001       G     -5.862926E-06     -4.551246E-04     -8.286275E-07 876
-CONT-                 -8.112655E-06     -3.389444E-08      5.149248E-06 877


these will both succeed:

/.+\n-CONT-/.match(line)
/.+-CONT-/m.match(line)
