Warning about '' being invalid integer in test

[zimme]

In __fundle_compare_versions there's a chance that $v1 or $v2 is empty which creates warnings with the -lt/-gt comparisons as an empty value isn't a valid integer.

I see that you check for the case when one is present and the other one isn't. However I don't know how to change the code so that it only does the -lt/-gt checks when both values are present.

I'm seeing this when running fundle self-update.

Thanks for reporting, this should now be fixed.
