Re: how-many/count-matches for non-interactive use

[Richard Stallman]

    This use *may* be deliberate.  Allout has a special "hot-spot" operation 
    mode, where the behavior of the movement functions varies depending on 
    whether or not you started from on top of a bullet glyph.  The thing is 
    that this behavioral nuance should not happen when being called 
    non-interactively.  It *may* be that the interactive-p conditioning is for 
    that purpose.

Perhaps that makes interactive-p useful in some of the commands.
However, when a function is not a command, it cannot be called
interctively.  (interactive-p) is equivalent to nil in such a
function.  So I don't see how the calls to interactive-p can do
something useful there.
