You can limit the replacement operation by selecting text first (depending
on your version of Emacs, you can either use the mouse or experiment with
commands such as C<C-SPC> to set the mark at the cursor location and

-Also, Stefan Kangas sent in the following tip about an alternate
-approach using the command C<indent-region> to redo the indentation
-for the currently selected region (adhering to indent rules in the
-current major mode). You can run the command by typing M-x
-indent-region or pressing the default keybinding C-M-\ in cperl-mode.
