TOC-cleanup does not handle tabs correctly #3

Currently tab characters confuse doc-toc--create-tablist-buffer, which is what C-c C-c runs from TOC-cleanup mode. The resulting TOC-tabular buffer has the incorrect levels for any entry that used tabs for whitespace.

Running (untabify) before creating the tablist buffer seems like the most reasonable solution. Another idea be to try (setq indent-tabs-mode nil) when toc-cleanup-mode first starts so that the user won't create tabs by mistake. Doing both wouldn't hurt.

Thank you for creating the issue. Untabify sounds like a wise thing to do indeed before creating the tablist (even though, technically, the manual speaks only of spaces). I have added it. Thanks again, also for the suggested fixes!
