It sounds like this is a bug in the field handling of line-move.
Would someone please investigate, then respond with the diagnosis?
I am not sure whether it is better to fix this or leave it alone,
but we should figure out what's wrong before deciding that.

I admit this is somewhat pathological --- but I've hit it a
couple of times when in directories that have long names (with
lots of white space chars in the dir name).
(you end up running into more and more of these as you rip CDs to
MP3)
If you have bash showing the working directory, for instance my
PS1 is
\t \h \W $
then after executing commands like ls in such a directory, c-p no
longer moves point past the recently displayed prompt.
Here is a test case, comprised the lines pasted from the shell
buffer, interspersed with comments:
#cd to /tmp and make a bogus directory there:
mkdir 'a directory with a very long file name '
18:27:21 labrador tmp $ cd a\ \ \ \ \ directory\ \ \ \ \ \ \ \ \ with\ \ \ \ \ a\ \ \ \ \ very\ \ \ \ \ long\ \ \ \ \ file\ name\ /
18:27:28 labrador a directory with a very long file name $ ls
18:27:39 labrador a directory with a very long file name $
#execute ls, after the next prompt is displayed, pressing c-p
leaves point trapped after the prompt. Hitting C-c C-p moves
prompt correctly to the line where ls was executed.

The trouble is that line-move-1 calls `beginning-of-line', then
(vertical-motion -1). On field on a continued line, this doesn't move
far enough, and we return to the original position when trying to
return to the old column. I installed a hack to work around this.
