Yes, see this code in the vim.vim indent file:

function GetVimIndent()
  " Find a non-empty line above the current line.
  let lnum = v:lnum - 1
  while lnum > 0
    if getline(lnum) !~ '^\s*$'
      break
    endif
    let lnum = lnum - 1
  endwhile

  " Hit the start of the file, use zero indent.
  if lnum == 0
    return 0
  endif

Perhaps, if this is a very common thing to do for indenting, I could make a
special function for it.  Should make the indenting a bit faster.
