<p>Also there is no need to strip trailing spaces, if the "strip trailing spaces" option is set then they go away when the file is saved anyway.</p>

<p>As for using anything other than ascii spaces for breaking, see the warning on the <a href="https://developer.gnome.org/glib/stable/glib-Unicode-Manipulation.html#g-unichar-isspace">link</a> <a href="https://github.com/codebrainz" class="user-mention">@codebrainz</a> posted.</p>

<p>Reflowing something containing tabs is hard to understand, why use a tab internally unless you want something aligned, but then you ask for it to be un-aligned <img class="emoji" title=":smile:" alt=":smile:" src="https://assets-cdn.github.com/images/icons/emoji/unicode/1f604.png" height="20" width="20" align="absmiddle">  I'm not sure what the "right" thing to do is, maybe better to not do anything special.</p>
