Yeah I agree, made it hyphens only.

Added a comment on the top of the file

Hmm, not sure at the moment. The nice thing as I understand it with the main method is I can code
it to grab the latest options when run, so if a new option is added in
OptionsDefinitions there should be no need to update the tab completion file generation.
I'm not too familiar with *.in files. I know it is used as an input file.
What would you recommend ?

Good catch :), this line is not needed at all, I was editing the tab-completion file I used
for thermostat and I seemed to have missed this line.
