bug#27932: 26.0.50; Feature request: prevent scroll commands from changing the buffer location of point

[Dani Moncayo <dmoncayo@gmail.com>]

Severity: wishlist

Hi,

I'd like to ask for a feature which I'm used to in other text editors
like notepad and notepad++ on MS-Windows (I think many other editors
may have it too).

I'd like to be able to configure Emacs so that scroll commands _never_
move point (cursor) from its _buffer_ location.

That could lead to situations where the point/cursor is not visible
(it is out of the visible portion of text).  In that situations, any
command which moves the cursor/point (e.g. C-f) or changes buffer text
should trigger an auto-scroll to get the point/cursor back to the
visible area (window), preserving its _buffer_ location.

That feature could be enabled by giving some special value (e.g.
'never) to the variable "scroll-preserve-screen-position".

I don't know how complex is that to implement, but I think some users
may like it.
