Enter, o and O give the new line the old one's indent as it is, tabs and all, as acme's autoindent does; a level more after an opening delimiter is a tab where the indent is tabs

The indent was rebuilt as spaces, partial levels dropped, so a tab-indented
line went on with spaces (or with one space, after Enter).
