Vim: can indentation use spaces after non-whitespace?

Is it possible to make VIM use spaces for tabs, when the cursor has non-whitespace characters before it?

eg:

(Assuming TAB is --->, • is a space.)

--->function(arg);••••••/* comment */
    //            ^ use spaces when pressing TAB after non-whitespace chars.

Otherwise I want real tabs when pressing tab.

This is useful when tabs are used for initial indentation, but the alignment for all text after uses spaces.

This is not possible to do automatically without scripting or a plugin.

The "Smart Tabs" plugin was designed for this task. http://www.vim.org/scripts/script.php?script_id=231

To make the problem happen a little less frequently there are the built-in preserveindent and copyindent options to prevent losing your existing tab indent when expandtab is set.

Use :set expandtab.
This will expand all tabs to spaces, during insert, even the ones at the beginning of the line (which probably is the best).
Use CTRL-V<Tab> to insert a tab.

From vim help (:help expandtab)

'expandtab' 'et'        boolean (default off)
                        local to buffer
                        {not in Vi}
        In Insert mode: Use the appropriate number of spaces to insert a
        <Tab>.  Spaces are used in indents with the '>' and '<' commands and
        when 'autoindent' is on.  To insert a real tab when 'expandtab' is
        on, use CTRL-V<Tab>.  See also :retab and ins-expandtab.
        NOTE: This option is reset when 'compatible' is set.

Use :set shiftwidth=4 (or :set shiftwidth=8) to control how many spaces are added per indent.

'shiftwidth' 'sw'       number  (default 8)
                        local to buffer
        Number of spaces to use for each step of (auto)indent.  Used for
        'cindent', >>, <<, etc.

Other settings of interest are softtabstop, tabstop and autoindent.
