hush: tighten up "for" variable name check.
Add TODOs. Disable redir4.right part where we differ from bash. It is not a bug per standards. Add a few tests, one is in hush-bugs section: and_or_and_backgrounding.right. It will likely bite users in real world usage.

+# UNFIXED BUG: hush thinks that ; && || & have the same precedence.

+# See example below.
+# Precedence of ; is not a problem in practice. Precedence of & is.

+#2.9.3 Lists
+#
+#An AND-OR list is a sequence of one or more pipelines separated by
+#the operators "&&" and "||" .
+#
+#A list is a sequence of one or more AND-OR lists separated by the operators
+#';' and '&' and optionally terminated by ';', '&', or <newline>.
+#
+#The operators "&&" and "||" shall have equal precedence and shall be
+#evaluated with left associativity. For example, both of the following
+#commands write solely bar to standard output:
+#
+# false && echo foo || echo bar
+# true || echo foo && echo bar
+#
+#A ';' or <newline> terminator shall cause the preceding AND-OR list
+#to be executed sequentially; an '&' shall cause asynchronous execution
+#of the preceding AND-OR list.
