`untabify' sometimes causes the cursor to jump. If you have a buffer like this, with (-!-) representing point:
^I(-!-)^ISome text some text some text
And (for example) have a before-save-hook that calls untabify on the
whole buffer, the cursor will jump to the beginning of line. This is a bit surprising.
