bug#45116: 26.3; refill-mode doesn't allow me to add text at the end of a paragraph

[David Klein]

Apologies. I didn't make myself sufficiently clear.

If I typed in the text 

"The quick brown

jumped 

over

"

and then went up to the end of the first line and type the characters '[space]' 'H' 'e' 'l' 'l' 'o'

I get

"The quick brownHello"

instead of 

"The quick brown Hello"

i.e. zero spaces instead of one. Only excess whitespace should be removed and the first space isn't excess.

Isn't that expected,, given that the doc string of this mode says:

                                             When enabled, the
  current paragraph is refilled as you edit.  Self-inserting
  characters only cause refilling if they would cause
  auto-filling.

"Refilled as you edit means excess whitespace is removed, no?
