 	* configure.in:
 		define READLINE_LIBS instead of linking libreadline
 		to every binary. 
 		AC_CHECK_LIB(pthread) was missing comma before
 		ACTION_IF_NOT_FOUND, thus have_libpthread was always no.
-	* mail/Makefile.am: User READLINE_LIBS
+	* mail/Makefile.am: Use READLINE_LIBS
 	* lib/argcv.[ch]: Treat a sequence of whitespace characters as
