How to get short option name from long option name in vim

Question

I have a list of vim long option names as strings (e.g. ["tabstop","shiftwidth"]). What would be the best way to convert it into a list containing only short names (e.g. ["ts,"sw"]). What about if the original list is a mix of short and long names?
