There are always going to be problems where the option name was
not fully specified on the command line (e.g. --compre 'foo') and
I had first wondered if it would be possible to echo what was
actually typed in. This proved to be too much effort.. Otherwise
you would actually have to remember the parsed item as well as
which option it mapped to...
Do you think option '--compression' is clearer?

Thanks for your time
Leo
