+Fix or remove broken or misguided default aliases:
 
-- Remove pointless default aliases 'fc' and 'type'; these are already
-  implemented as normal shell builtins. Add man page entries for these.
+- Make a proper POSIX 'hash' builtin command and remove the builtin alias
+  hash='alias -t --', which, when removed, exposes a b0rken 'hash' builtin.
+  To work with this alias, the 'alias' builtin parses the '-r' for 'hash'
+  *after* '--' ('alias -t -- -r'), which is utterly bogus and violates POSIX.
+
+- Make a proper builtin out of the redirect='command exec' alias. It should
+  really only parse redirections. Currently, if an unwitting user notices this
+  alias and tries out something like 'redirect ls >file', it does 'exec ls
+  >file', so 'ls' replaces their shell and they get logged out. That is so
+  misdesigned I'm calling it a bug.
+     Alternatively, maybe just get rid? Who uses this anyway? 'redirect >&2'
+  takes four more keystrokes to type than 'exec >&2'.
+
+- Make proper builtins out of the following scripting-related aliases, so
+  that 'unalias -a' does not eliminate them. If done correctly, this causes
+  no other change in behaviour. It would be good practice to 'unalias -a' in
+  a script to start with a clean slate, except ksh has always made that
+  impossible without losing these. Default aliases should be to facilitate
+  interactive use.
