Details:

Consider the makefile

pat=$(filter-out %/,$(subst /,/ ,$@))

target/%::
        @echo "$(pat) 1"

target/%::
        @echo "$(pat) 2"

target::
        @echo "test 1"

target::
        @echo "test 2"

I'd hoped that "make target/test" would run the two double-colon pattern
rules, like "make target" does. However, this appears not to be the case. If
this is a bug or not is definitely a matter of opinion, but having this
feature would certainly be useful to me..

Regards
D.
