Katsnelson" <kkm(a)kis.ru&gt; writes: `untabify' is an interactive compiled Lisp function -- loaded from "tabify" (untabify START END) Documentation: Convert all tabs in region to multiple spaces, preserving columns. Called non-interactively, the region is specified by arguments START and END, rather than by the position of point and mark. The variable `tab-width' controls the spacing of tab stops.
