When the bépo layout is set from the `keyboard-layout` layer, the
message `(wrong-type-argument keymapp nil)` shows up. After some
digging, it turns out Spacemacs tries to set shortcuts for `nil`
`map` variables in this function.
This commit ensures it is impossible to try to set a shortcut for an
inexisting keymap.
This commit has been tested with Emacs 27.0.90.
It also removes an unused `if` statement
keyboard-layout was broken by commit da80634, which replaced cl by
cl-lib. Some function calls weren’t replaced. There may be old calls
remaining in other layers.
- Base Remapping Keys
`#{n, e, i, o}` <=> `#{h, j, k, l}`
- setting `avy` keys to the `colemak` home row keys
`#{a, r, s, t, n, e, i, o}`
- adjusting leader key to `tn`
- overriding evil org mode bindings especially for 'o'
- one character key guess rebindings can give back empty string
when looking for the prefix and it isn't empty, then guess the rebindings --
this fix lets the check not pass and return `'(nil nil)`, allowing the
`(remove-if #'null)` to actually work.
- correcting magit staging when using visual line
