tests: non alphanumeric characters in input

Make: remove part of EVAL breaking # and $

step0: no MAL character must break the interpreter
       (soft) no printable ASCII character either

step1: no MAL character must break strings
       (soft) no printable ASCII character should break strings
       (soft) no character should break comments

step6: redo step1 tests for comments inside read-string, as new
       problem may occur with line breaks and escape characters of the host
       language.
