## reindent-region

Arguments: lisp-edit-pane &key pretty-print

Reindents the selected lisp code or top-level lisp form in the specified `lisp-edit-pane`. If any text is currently selected, then that is the text that will be reindented; otherwise the top-level form that the text cursor is inside (or after) will be reindented.

If pretty-print is `nil` (the default), then spaces are simply added to or removed from the beginning of each line as needed for conventional lisp source code indentation. If pretty-print is true, then the top-level form is pretty-printed as a whole into the lisp-edit-pane (fitting the text to the current window width), replacing the previous version of the form. Pretty-printing will likely wrap the form differently (changing how much code appears on each line), and will always remove any comments that were in the top-level form.

The text cursor should end up in the same logical position as before the operation if pretty-print is `nil`; this is not feasible if pretty-print is true. In either case, parenthesis-matching will be updated after the operation (see parentheses-matched).

Reindenting may not work correctly if the text is auto-wrapped. Auto-wrapping will happen if the `lisp-edit-pane` has no horizontal scrollbar and one or more of its text lines is longer than the interior width of the window. Therefore, a `lisp-edit-pane` in which reindenting will be done should have a horiztonal scrollbar by setting its scrollbars property either to `:horizontal` or (more typically) to `t` (which is the default).
