bug#67470: 29.1; move-end-of-line behaves badly with eglot type annotations

[matthewktromp@gmail.com]

1. Go to a buffer with some code
2. Start eglot
3. Eglot adds type annotations
4. Go to some line that ends with a type annotation
5. Press C-e to go to the end of the line
6. Navigate around with C-n and C-p
7. Note that point will jump to the column of the position of the end of
the type annotation, rather than the end of the code.

For instance, if you have some code and some annotations (represented
with a) like so, with point at |:

some|code aaaaaaaaaa
here are some more lines which do not have annotations

Pressing C-e will move point to the end of the line

some cod| aaaaaaaaaa
here are some more lines which do not have annotations

Then when you press C-n, instead of point moving to the same column in
the next line, like so:

some code aaaaaaaaaa
here are|some more lines which do not have annotations

It will instead jump to the column of the end of the annotation, like
so:

some code aaaaaaaaaa
here are some more |ines which do not have annotations
