Yeah, I forgot to repeat it in this message, but the above
three-bullet list needs the 0-th item

 - If <name> has already colon in it, following special case rules
   do not apply.

in front of it.

Even though I suspect the updated behaviour may be more useful for
casual users (while making the semantics a bit more difficult to
explain, like the above documentation update), it is a major
regression to existing users if it closes the last escape hatch, so
I guess with your patch we are almost there but not quite there yet.
