Spinoff from #31414, about int entry fields.  It claims: Note: a deeper problem is attaching a tracer that get called with each keystroke.  Using a StringVar avoids the error when the entry is blanked, but currently allows non-ints to be saved.  A better solution would be to not do the auto tracing, but use a IntVar and only call var_changed when the user 'leaves' the box, after checking for a count in a sane range.

Verify claim and proposed solution.
