And it does: it redisplays the current window. It does _not_ always redisplay other windows, and does _not_ redraw the entire frame unless another argument tells it to do so. IOW, "redisplay" is not the same as "redraw the frame". If the argument's name were "redraw-frame", then I'd agree with you that the name is misleading. > > Renaming the argument as you propose would be a step backwards, since > > it describes the _purpose_ (as opposed to _effect_) of that argument, > > and that could easily change with further development, and is not > > accurate even with the current code. > > Other commands that use the argument name 'interactive' have the same > assumption of describing the purpose, not effect. It is possible that in other cases that name is the best one we found; or it could be that some of those arguments need to be renamed to something else. The decision is on a per-case basis, and cannot be global.
