# The hash builtin is most used for the command hash table, which is
# populated automatically.  This is therefore highly system specific,
# so mostly we'll test with the directory hash table: the logic is
# virtually identical but with the different table, and furthermore
# the shell doesn't care whether the directory exists unless you refer
# to it in a context that needs one.
