Comment (by ryandesign@…):

 Updated in r98335.

 I didn't understand why the post-destroot block of the doc variant was so
 complicated so I simplified it.

 I also removed the unnecessary --mandir configure arg.

 Now I need to find all ports using icu and increase their revisions to
 rebuild them...
