The function modify-editor-pane-buffer
modifies the editor-pane
pane
according to the keyword arguments.
The argument contents (if non-nil) supplies a new string to place in the buffer.
If
fill
is non-nil the editor fills each paragraph in the buffer. If
fill
is a fixnum then the buffer is filled at that width. If
fill
is :default
(the default value) and
fixed-fill
is supplied then the value
fixed-fill
is used. Otherwise the buffer is filled to the window width.
The argument
flag
is deprecated. You can supply the initarg :flag
when creating an editor-pane.
