BINDINGS format:
<DELIMITER_KEYWORD>

<DELIMITER_KEYWORD>
<BINDING_FORM>

...
DELIMITER_KEYWORD - specifies a type of following <BINDING_FORM> (or forms).
Currently supported types: :major, :minor and :global.
:major and :minor bindings have this shape:
(<MODE>
<OPTIONAL_DOC_STRING>
<PREFIX_OR_BINDING>
<PREFIX_OR_BINDING>
...)
:global forms have a similar shape:
(<OPTIONAL_DOC_STRING>
<PREFIX_OR_BINDING>
<PREFIX_OR_BINDING>
...)
<OPTIONAL_DOC_STRING> is a string that will be used to generate a key-bindings
section in the corresponding README.org files.
<PREFIX_OR_BINDING> is a recursive form that can be:
A prefix form:
(<PREFIX_KEY> <TEXT> <PREFIX_OR_BINDING>)
Or a key-binding form:
(<KEY> <FUNCTION_SYMBOL> <TEXT>)
<TEXT> is what will be displayed in the menu and used for the documentation
generation.
<PREFIX_KEY> and <KEY> are singular keys represented as strings.
<FUNCTION_SYMBOL> is the function that will be bound to the <KEY>.
See core-spacebind-utest.el for examples.
NOTE: This macro also has `use-package' integration via `:spacebind' key
\(fn <<DELIMITER_KEYWORD> <BINDING_FORMS>...>...)"
