Re: simple patch for `etags.el'

[Richard Stallman]

    (defun make-progress-reporter (format-string
                                   min-value max-value &optional current-value)

This could be a useful feature.  I think there should be arguments
MIN-CHANGE and MIN-TIME to specify how often to redisplay the
percentage--for instance, I could specify 5 for MIN-CHANGE meaning "no
less than 5% change", or 1.0 for MIN-TIME meaning no more than once
per second.

Aside from that, it looks clear, but there needs to be an explanation
of the detailed format of the format of the `reporter' data structure.


These functions would go in subr.el.
