Not quite sure if this name/concept is right as an argument, kept it for the sake of consistency but happy to adjust if someone has a better idea!

This basically allows for the context to continue to be parsed. Malformed flags will still be ignored and not part of the set, which is what v2 pre-release builds did.

OH! Actually! I have a better idea: can you change this code to pass shellComplete into the parseIter function, ignore the errors inside the function itself, and add the descriptions I just requested inside the function's docstring?

Great idea!
- Changed the signature of
parseIterto accept a fourth parametershellComplete boolto deal with nil errors within. - Decided to keep the
shellCompletename, played withignoreErrorsinstead, but it felt like a misnomer sinceset.Parsewon't actually error on it. - Modified a couple of consumers to pass
shellCompletefrom their own context as well. - Added a couple of lines to the docstring, hope my wording conveys the use for passing that argument.

Add description to that function's docstring, and delete extraneous space
Fixes #944
