Invoking C-x C-f (spacemacs/helm-find-files) right after startup, before helm is
loaded, caused a void function error for helm-current-directory. This fixes it.
Fix issue #6416: SPC s f (spacemacs/helm-files-smart-do-search) in a buffer
that is not visiting a file causes an error:
Wrong type argument: stringp, nil
* layers/+completion/helm/funcs.el
(spacemacs//helm-do-grep-region-or-symbol): Check whether preselection is
nil in order to avoid calling helm-basename on a nil value.
- Apply `/` and `//` rules (double / is for private functions)
- Add missing `spacemacs/` prefixes
- Move functions used outside of spacemacs-base layer to
core/core-funcs.el
- Remove unused functions
Commit originally intented to only rename linum-update-window-scale-fix
to spacemacs/linum-update-window-scale-fix :-)
