bug: gengetopt --show-help with continued lines

Hi

I found that "gengetopt --show-help" cannot work with continued lines
illustrated in the example:

  $ gengetopt --show-help -i sample0.ggo
  sample0.ggo:10: syntax error \
  sample0.ggo:10: section "more involved options" \
  sample0.ggo:10:                                 ^

   option  "funct-opt"       F "A function option"    optional 

The sample1.ggo came along the package and works fine. 

Is this a bug?

thanks
