Support arg synonyms? #64
Description
E.g. declaring that -C is an alias of --cfg.
- Could be very handy for apps, to offload the processing (esp. consistently handling override precedence!...)
- But normalizing the query interface across them (e.g. to "only ask about the long form") would open a whole new can of worms for the current simplistic level of implementation, which doesn't even have a unified representation for short/long opts...
- Also, what if more than 2 are the same? (The declaration method alone could become too complex in no time...)
