Details:
With this makefile:
foo/%/baz:
@echo "Prereq - stem $*"
foo/%/baz/thing.txt: foo/%/baz
@echo "Good match - stem $*"
foo/%:
@echo "Bad match - stem $*"
I'd expect the shortest stem (bar) to be matched as follows:
> make foo/bar/baz/thing.txt
Prereq - stem bar
Good match - stem bar
However, it matches the longer stem (bar/baz/thing.txt) instead:
> make foo/bar/baz/thing.txt
Bad match - stem bar/baz/thing.txt
The makefile works as expected if either removing the "Bad match" rule or the
prerequisite from the "Good match" rule.
