Hi,
  I'm trying to create a manpage where the command takes a flag "?"
The command would (to display help):
  module -?

For this I created in module.1:

.Bl -tag -width Ds -compact
.It Fl h , ? , H , -help
Show the help message.
.El

But the output of this looks:

     -h,?, -H, --help
             Show the help message.

Without the - before ?

Can anyone tell how I can display a -? before the flag?

Thanks,
Aisha
