A few more bits of info: - I think the freeze is entirely temporary, however the time frozen = *seems* to increase linearly depending on the number of offending lines, = so a buffer with only one or two extending lines might recover in a = second or two, but a buffer with many offending lines will appear = permanently frozen. - Move attempted point motion on offending lines appears to prolong the = freeze. - The freeze will be very minimal (a second or two) if point skips over = the wrap-prefix text entirely, e.g. apply wrap-prefix to lines in the = middle of buffer, then M-> to eobp. - No freeze occurs if point is at eobp and moves back to bobp with M-< = in the same circumstances as above. - The freeze will occur if the wrapped text is scrolled into view from = below, e.g. same circumstances as above, move point to eobp then mouse = wheel up. - When point moves to an affected position and things become frozen, the = line number in the mode line will display as "??"
