What about the idea blow ?

  - show abort message "there are outgoing revisions which may confuse
    users" (and the hint to lead users to "hg help histedit"), and

  - explain more detail about "--outgoing", like:

      For safety, this command is aborted, also if there are outgoing
      revisions which may confuse users: for example, there may be
      another unexpected outgoing branches, if number of "root
      revisions in outgoings" is two or more.

      Use "min(outgoing() and ::.)" or similar revset expression as
      ANCESTOR instead of "--outgoing" option, to specify only one
      root of outgoing ancestors of the working directory in such
      ambiguous situation. Please see :hg:`help revsets` for detail
      about selecting revisions.


I hope revise for messages by native speakers :-)
