# Tests for the :P variable modifier, which looks up the path for a given
# target.
+#
+# The phony target does not have a corresponding path, therefore ... oops,
+# as of 2020-08-23 it is nevertheless resolved to a path. This is probably
+# unintended.
+#
+# The real target is located in a subdirectory, and its full path is returned.
+# If it had been in the current directory, the difference between its path and
+# its name would not be visible.
+#
+# The enoent target does not exist, therefore the target name is returned.
