Comment (by aduth):

 Replying to [comment:16 dd32]:
 > It looks like the code in [attachment:42531.2.diff] is really only an
 optimisation, to skip processing text when not needed (as TinyMCE will
 wrap it in a paragraph tag anyway).

 me.

 Noting that there is a change in behavior after 42531.2.diff

 Before:

 {{{
 switchEditors.wpautop( 'Foo' );
 // "Foo"
 }}}

 After:

 {{{
 switchEditors.wpautop( 'Foo' );
 // "<p>Foo</p>\n"
 }}}

 However, the "After" case now more closely mimics the PHP behavior (which
 has the same result). Still worth noting that there is a difference with
 potential impact.
