[#14] Avoid "dot in path" hickup

[hidden-primary-net]

Do not interpret "." in path names as a file extension.

Thanks for your merge request @hidden-primary-net, but I have to reject it.

This would be a patch which, in my opinion, does the job slightly better:

I'll try to make a fix and a new release somewhere today, that might include a fix for #14 as well.

Thanks for your contribution either way!
