Relative path ".:" does not work

[shimmtak]

Hi. Thank you for your useful tool.
Using relative path to specify name space like below, it does not work.

{{blog>.:myblogspace}}

When I placed a blog at
Dokuwiki_Root/some/path/myblogspace/*
and placed the blog syntax at
Dokuwiki_Root/some/path/showblog.txt
The showblog page does not show any articles.

It works only when I place them at
Dokuwiki_Root/myblogspace/*
Dokuwiki_Root/showblog.txt

The environment : “Greebo” on PHP 5.6.21. CentOS7 (4.14.33-300.1.1)
