# 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.
