Re: Tentative diagnosis of TMM's problem. [Re: Enabling Transient Mark Mode by default]

    Strongly agreed!  It should be obvious, really - using Emacs with TMM is
    so radically different from using it without, that it's difficult to
    imagine anybody not being unhappy with (at least) one of these options.

I am surprised by that statement.  With mark-even-if-inactive set, the
difference is small.  What difference are you talking about that you
think is "radical"?
