WG: 26.1; Problems with flyspell-region |

I mentioned some problems with flyspell-region on the help-gnu-emacs mailing
list here:
https://lists.gnu.org/archive/html/help-gnu-emacs/2018-07/msg00100.html
Issues are:
Issue 1) The spell check is performed just once, and is not updated as I type
inside that region. This is what I wrote on the mailing list:
"If I mark a region (click on the beginning, hold shift, move to the end), and
then run flyspell-region, the region gets spell-checked, and all the dictionary
misses are underlined in red, as expected. But then, if I fix the words, the
spelling marking (the red underlining) is not removed. It looks like Flyspell
is not 'live' anymore within that region. The "overlay" is left behind as
static font faces."
I do not want to activate Flyspell for the whole buffer, because that would
lead to too much red underlining.
If I just wanted a single-shot, I would use ispell-region instead.
If this cannot be fixed, the current behaviour should be documented.
Issue 2) There is no easy way to remove the red underlining (overlays) left
behind by flyspell-region. This is what I wrote on the mailing list:
"Often I get too many dictionary misses (too much red underlining). Or I just
do not want to be distracted anymore. That is the reason why I want to be able
to turn spell-checking on and off on demand on a particular region. And, when I
want it off, I want to remove the "overlays" from that region. Why should they
remain? At the moment, there is no direct way to do that."
I also wrote:
"After some searching, I found out about flyspell-delete-all-overlays and
flyspell-delete-region-overlays, but alas, they are not marked as
'interactive'. I wonder how Flyspell thinks users should remove those marks
(how to end the flyspell-region command)."
Issue 3) Disabling flyspell-persistent-highlight renders flyspell-region
useless.
Contrary to some of the answers in the mailing list, that combination does not
work at all. This is what I am seeing:
"What I mean is that, if you turn flyspell-persistent-highlight off, then
flyspell-region does nothing other than consume CPU cycles. The red underlining
for dictionary misses does not show up at all."
Again, I do not want to turn on Flyspell for the whole buffer. If
flyspell-region is supposed to work only when the Flyspell Mode is active, it
should check, and error if it is not active. But that kind of defeats the
purpose of having a flyspell-region.

I fixed this blunder, and I'm marking the bug done.
Thanks for your report and suggestions.
