    _______________________________________________________

Details:

The handling of $* is unexpected as it differs between the second expansion of
the targets and the recipe.


$ cat Makefile 
.SECONDEXPANSION:
%x: $$(info $$*); : $*


For examples such as treated in the manual, this works as expected:

$ make fox
fo
: fo


However, following the suggestion about path treatment in implicit rules, the
following is unexpected:

$ make q/ux
u
: q/u


Observe the directory being stripped only in the expansion of $* in the target
listing, but not in the recipe.
