Update current layout's workspaces before saving layouts to file (fixes
7214).
Load current layout's workspaces after loading layouts from file, if it's
one of the loaded layouts (fixes 6979).
This fixes two issues regarding layouts.
1. Since Bad-ptr/persp-mode.el@e950bf15, persp-mode requires setting
persp-hook-up-emacs-buffer-completion in order to install the hooks for
ido & friends. This variable is nil by default, making SPB b b not
restrict to layout-local buffers.
2. The function spacemacs-layouts/non-restricted-buffer-list removes a
hook and re-adds it later. This makes the assumption that the hook was
already present. If it was not (due to 1) then SPC B b changes global
state by adding that hook. Instead, just let-bind the hook variable
for the scope we need it changed.
This explains and partially fixes#5788 and #6266. It does not fix the
dependency on ido-mode. If ido-mode is excluded, persp-mode will not
install the hook for ido, and SPB b b will still be unrestricted.
For example, creating new custom layout `["e" . "Name"]` clashes with
`["e" . "Spacemacs"]`. After override `SPC l o` should not show both of
them, but only the override.
Use two different sets of workspaces for each perspective - one
set for graphical frames, and one set for terminal frames.
This is required because workspaces from graphical frames are not
compatible for use in terminal frames.
- add `l` to workspace transient state to go back to layout transient
state
- remove erroneous `l` and `h` keys on layouts transient state
- unique documentation toggle for layouts and workspaces
- reformat and sort transient states documentation
