After a `*word*` or `_word_` span is converted on a space, punctuation
or Enter, the word without its marks is AutoCorrected as before:
replacements, capitals, ordinals and links (`*teh* ` becomes bold
`The `). Undo right after still restores the marks in one step, and
after Enter the Enter stays. A marked web address becomes a link
without carrying its bold or italic into the text typed after it.
