   do_int_spell_fix()

+	  defined and DISABLE_SPELLER isn't.  Also, turn the USE_REGEXP
+	  flag off during spell checking in order to avoid a potential

   justify_format()
 	- For more compatibility with Pico, remove extra space after a

+	- If NANO_SMALL is defined, don't bother checking the
+	  CASE_SENSITIVE flag or using its value when compiling a list
+	  of matching regular expressions. (DLR)
   search_init()
 	- Add parameter use_answer.  When it's TRUE, only set
 	  backupstring to answer.  This is needed to preserve the text
