# Tests for the :tA variable modifier, which returns the absolute path for
# each of the words in the variable value.

# TODO: Implementation

# Between 2016-06-03 and 2020-11-14, it was possible to trick the :tA modifier
# into resolving completely unrelated absolute paths by defining a global
# variable with the same name as the path that is to be resolved.  There were
# a few restrictions though: The "redirected" path had to start with a slash,
# and it had to exist (see ModifyWord_Realpath).
#
# This unintended behavior was caused by cached_realpath using a GNode for
# keeping the cache, just like the GNode for global variables.
