      assignment statements as arguments from expanding them as
      assignment statements; when not in POSIX mode, assignment builtins
      lose their assignment statement expansion properties when preceded
      by 'command'.

      'SIG'.

      signal specification and revert the signal handling to the original
      disposition if it is, unless that argument consists solely of
      digits and is a valid signal number.  If users want to reset the
      handler for a given signal to the original disposition, they should
      use '-' as the first argument.

      for the filename argument if it is not found by searching 'PATH'.

      'inherit_errexit' option, so subshells spawned to execute command
      substitutions inherit the value of the '-e' option from the parent
      shell.  When the 'inherit_errexit' option is not enabled, Bash
      clears the '-e' option in such subshells.

      option, so numeric arguments to 'shift' that exceed the number of
      positional parameters will result in an error message.

      display them with a leading 'alias ' unless the '-p' option is

      display shell function names and definitions.

      variable values without quotes, unless they contain shell
      metacharacters, even if the result contains nonprinting characters.
 
-  48. When the 'cd' builtin is invoked in LOGICAL mode, and the pathname

      constructed from '$PWD' and the directory name supplied as an
      argument does not refer to an existing directory, 'cd' will fail
      instead of falling back to PHYSICAL mode.

      of the pathname constructed from '$PWD' and the directory name
      supplied as an argument exceeds PATH_MAX when all symbolic links
      are expanded, 'cd' will fail instead of attempting to use only the
      supplied directory name.

      the current directory, even if it is not asked to check the file
      system with the '-P' option.

      file as having been found, though the shell will attempt to execute
      such a file if it is the only so-named file found in '$PATH'.

      the 'v' command is run, instead of checking '$VISUAL' and
      '$EDITOR'.

      interpret any arguments to 'echo' as options.  Each argument is
      displayed, after escape characters are converted.

      and '-f' options.

      interrupt the 'wait' builtin and cause it to return immediately.
      The trap command is run once for each child that exits.

      has been set.  If Bash receives a trapped signal while executing
      'read', the trap handler executes and 'read' returns an exit status
      greater than 128.

+  58. Bash removes an exited background process's status from the list
      of such statuses after the 'wait' builtin is used to obtain it.
 
    There is other POSIX behavior that Bash does not implement by default
