The scripts that generate the litmus tests in the "auto" directory of
the https://github.com/paulmckrcu/litmus archive place the "Result:"
tag into a single-line ocaml comment, which judgelitmus.sh currently
does not recognize.  This commit therefore makes judgelitmus.sh
recognize both the multiline comment format that it currently does
and the automatically generated single-line format.
