If t, hitting TAB always just indents the current line. If nil, hitting
TAB indents the current line if point is at the left margin or in the
line's indentation, otherwise it inserts a `real' tab character \(see

within literals \(comments and strings), but the line is always
reindented.

tab character will be inserted, or the equivalent number of spaces.
