How to make move-to-column with force option in Emacs insert spaces instead of tabs and spaces

Question

When using (move-to-column col t) with column argument larger than end-of-line Emacs inserts a combination of spaces and tabs, depending on whether col ends on a tab stop or not.

How can I make it insert only spaces?

You need to set indent-tabs-mode to nil , either using setq-default :

(setq-default indent-tabs-mode nil)

or customize :

(custom-set-variables '(indent-tabs-mode nil))
