+	  _rl_to_lower actually results in a different key sequence

+	  bound to the result of _rl_to_lower for that key are both
+	  rl_do_lowercase_version, just insert the key into the search string

+	- read_a_line: if heredoc_string is non-zero, use shell_getc instead
+	  of yy_getc to get the right alias processing
+	- shell_getc: if heredoc_string is non-zero, don't add a space to the
+	  end of the alias -- it can mess up the here-document delimiter if
+	  the next character is a newline
