program aborts when adding options with short commands longer than 1 char

[tigerplush]

I added the option

    uint64_t speciations_per_habitat;
    app.add_option("-sph,--speciations-per-habitat", speciations_per_habitat, "how many events should be simulated before simulation stops")->required();

and it just threw

I changed it to

    uint64_t speciations_per_habitat;
    app.add_option("-t,--maxt", speciations_per_habitat, "how many events should be simulated before simulation stops")->required();

and now everything works.

having dashes in the long command leads to the long command not beeing recognized. so even if I had kept --speciations-per-habitat, the cli parser would ask for the option even if had added it into the command line

-sph is likely the cause of the problem. That is a non-standard option name. Short options with more than 1 character are not allowed unless you enabled them with .allow_non_standard_option_names() on the app. This was added not that long ago in the code for main.
