If add template "Subst:TName" then open template editor
if template without templateData then text "text may be on template page" and link to "Template:Subst:TName"
link should be "Template:TName" and "Subst:" should be cut
Also, the documentation can not be read from Template:TName/doc because it is trying to read from Template:Subst:TName/doc
Also, when writing in the search template name "Subst:TNa...", then there is no drop-down list

I think that we have a task somewhere else to allow users to determine substitution status properly (i.e. with an actual input control), rather than having to append 'subst:' which breaks in the ways you describe here.
