tests/hard_coded/*.m:
Update programming style, unless doing so would change
the meaning of the test, in particular:
- use '.' as a module qualifier in place of '__'
- use {write,print}_line where appropriate
- use if-then-else in place of C -> T ; E
- use state variables in place of DCGs
tests/hard_coded/dir_test.m:
Document what the expected outputs correspond to.
Use a uniform module qualifier in the output.
tests/hard_coded/dir_test.exp*:
Conform to the above change.
