List-Unsubscribe: , List-Archive: Xref: main.gmane.org gmane.emacs.devel:8130 X-Report-Spam: http://spam.gmane.org/gmane.emacs.devel:8130 The output of C-h v end-of-line contains the following line: if N is nil or 1, and point starts at a field boundary, point does not move. This is not quite accurate: there is an exception. Point does not move *unless* the previous character has a non-nil rear-nonsticky text-property *and* a text-property field eq to boundary. Then point *does* move over the field. Comint and its derived modes rely heavily on this exception. Actually, although the description of the situation is correct, my interpretation of it was, I believe wrong. If point is at the beginning of a buffer, or after a character with a rear-nonsticky field property, different from the following character's field property, then I believe C-e should move point over the following field, regardless of whether the previous character's field property is `boundary'. I checked that this actually was the behavior in emacs-21.2.90. The problems I described do not occur in 21.2.90. So maybe it might be good to revert to the 21.2.90 behavior. Sincerely, Luc.
