I assume that you simply want to indent the left margin by 4, 8, 12,
etc., spaces.  As has been pointed out, ":set tabstop=4" will not work,
because it redefines the meaning of tabs instead of using spaces.

What you want is

	:set shiftwidth=4	(:set sw=4), possibly combined with
	:set autoindent		(:set ai)

Now, DON'T use the tab key at the left margin; use ^T instead.  Each ^T
will move 4 positions to the right (inserting combinations of tabs and
spaces to get to the correct column).  Each ^D at the left margin will
move 4 positions to the left.

(I suppose you could map TAB into ^T if you wanted to).

As an extra bonus, you can now use the "<" and ">" commands to shift a
previously-typed block of lines left or right.

	>>	will shift 1 line
	6>>	will shift 6 lines
	>}	will shift everything to the end of a paragraph
	>%	if the cursor is over a brace or parenthesis, will shift
		    everything until the matching brace or parenthesis.
