thanks for the report!
As it turns out, the "make docs" command was actually not supposed to be
used that way. I committed a fix in which the "docs" target of the
Makefile calls the "zotonic generate-edoc" command, which is the correct
way of generating the documentation.
This will be part of the next bugfix release of 0.8. The diff of makefile:
- @erl -noshell -run edoc_run application '$(APP)' '"."' '[]'
+ bin/zotonic generate-edoc
