Bug fixes:
* We now emit the text equivalent for an emoticon when {{{thingsToInclude.attachmentTextEquivalents}}} is true (not always the right one, but that bug is in other code). Fixes #4420.
* We were passing {{{NO}}} to {{{elementWithAppKitAttributes:attributeNames:elementContent:shouldAddElementContentToTopElement:}}}; that's wrong, because that argument takes a pointer. We now pass {{{NULL}}} instead.
* Removed unnecessary {{{runRange.length = 1}}} assignment. It's already 1 for every image.
