getopt 1.20.3

Now by default getopt won't override a user specified opt argument if argv is in the global environment. Will continue to use argv as a default for opt if it is in the global environment and the user does not specify an opt argument (for littler compatibility).

getopt 1.20.2

Now allows one to pass an empty string to a character option. Thanks Matthew Flickinger for bug report.

getopt 1.20.1

Now explicitly imports the na.omit method from the stats package. Thanks Derrick Oswald for bug report.
Improved parsing for negative numbers preceded by a space instead of a '=' sign.
Thanks Roman Zenka for improved regular expression.
Slightly more informative error message if storage.mode coercion results in an NA. Thanks Roman Zenka for suggestion.
