Hi,

Just noticed commit of flyspell.el 1.91 and a problem in it. In function
flyspell-external-point-words flyspell-large-region-beg is not moved
after successful match. That makes that for buffers like 

ispella
ispella
ispella

only first match is found and tagged as misspelled since all further
searches start from the same point.

I am attaching a possible patch for that,
