Local includes are not working as intended

[gmcabrita]

Consider two local files Makefile and foo.mk

Makefile:

include foo.mk

foo.mk

foo:
	@echo "foo"

make allows including the local file, but mmake seems to think it's a remote include.

$ make foo
foo
$ mmake foo
   ⨯ installing                error=installing "foo.mk": only github.com is currently supported
