[PATCH] diff for mg's dired annoying issues

[Loganaden Velvindron]

Hi,

Using scrolling in dired causes a dot reset for
forward/backward page.

This diff fixes this annoying behaviour for
forward/backward page, beginning/end of buffer,
and goto-line.

Please test & report.
As usual feedback for improvements is welcomed ;-)
