Buffer view relocate should be improved #1790
Description
Description of the problem or steps to reproduce
When cursor is moved to a location which is far away (e.g. after a search, a goto line, or when opening a file at a given line), the view is always relocated in such a way that the cursor is at the bottom or at the top (minus scrollmargin), i.e. as if we just scrolled to this location. It is not like in other editors, and IMHO it is annoying. When we jump to a new location far away, we usually want to see more of its context, so the cursor should be placed closer to the center of the view, not near its edges. Certainly not near the bottom.
I suggest doing it similarly to other editors:
- If the distance between the new and the old location is less than one frame (i.e. the view either doesn't change or is just "shifted") then the current behavior is ok.
- Otherwise the current line should be at the center (like in vim, emacs and nano) or e.g. at 25% of the window height (like in gedit and geany). I'd personally opt for 25% of the height. Or it can be made configurable.
