Actually I don't see anything stating that during implicit rule search only global
VPATH is used. May be this should be explicitly reflected in the documentation
(I've checked VPATH/implicit rule search sections too)

I've had a quick look at the sources of make 3.79.1. In the 'file' struct there's a
char* vpath variable which, afaict, is unused right now. Moreover, when finding
implicit rule per-target variable list is already available. If I ever make patch to
take
per-target VPATH in consideration when finding implicit rules, how big are chances
that it gets to the future version of gmake?
