My fix in #27 wasn't correct.
Using
!versionto check if the version flag is specified is not correct asversionis a pointer. It could be!(*version)instead but I am not prepared to use that, or the betterversion->count(). However it is better to just use anelseof the previousif (version->count())so this is what I have done.
