12.3.15 New ways to control line wrapping in editor-pane

capi:editor-pane now supports three new initargs controlling line wrapping of the text it displays:

:line-wrap-marker specifies the marker to display at the end of a line that is wrapped.

:line-wrap-face specifies the text style to use to display the marker.

:wrap-style allows you to control whether long lines are wrapped normally (that is, splitting words), or wrapped at spaces so that whole words are displayed, or simply truncated.

Compatibility Note: The :wrap-style initarg supersedes editor:set-window-split-on-space , which is deprecated.
