The motivation is to clean redundent actions and bring more consistency
between `SPC b` and `SPC w` by:
- using capital letters for ace-window actions
- reusing the same letters between window and buffer when possible
- adding support for universal prefix argument to delete both window
and buffer
Details of changes:
Buffer
- `SPC b k` has been removed since the functionality is
available directly in Helm by selecting the kill buffer action
- `SPC b m` (buffer move) has been removed because the functionality
is available via `SPC w` with `SPC w h/j/k/l`, `SPC w H/J/K/L` and
`SPC w M` (see window section for the new `SPC w M`).
- `SPC b K` (kill other buffers) is now `SPC b m` to map with `SPC w m`
(kill other window or maximize). Using the universal prefix argument
`SPC u SPC b m` will also kill the windows.
- `SPC b C-k` (kill buffer matching regexp) is now simply on `SPC b k`.
- `SPC b D` now kills a buffer using ace-window.
- `SPC b d` and `SPC b D` now accept an universal prefix argument to
also delete the window. So `SPC u SPC b d` and `SPC u SPC b D` delete
the buffer and the window.
Window
- `SPC w M` now swap the window using ace-window.
- old `SPC w M` (center window) is now on `SPC w c` and `SPC w C` uses
ace-window.
- `SPC w SPC` (select window) is now on `SPC w W` since it uses
ace-window.
- `SPC w d` and `SPC w D` now accepts an universal prefix argument to
delete the window and the buffer.
This works with systems defined by the error delegate function (and it
shows which system is used, and which buffer supplies the “errors”).
When the Emacs next-error system is used and the next-error buffer is a
Spacemacs GNE buffer, it also shows current number / total number.
