  &quot; Give up if this line is explicitly joined.

  &quot; If the current line is a stop-block statement...
  if getline(v:lnum) =~ '^\s*\(end\|else\|elseif\|case\|otherwise\|catch\)\&gt;'
    &quot; See if this line does not follow the line right after an openblock
    if getline(plnum) =~ '^\s*\(for\|if\|else\|elseif\|case\|while\|switch\|try\|otherwise\|catch\)\&gt;'
    &quot; See if the user has already dedented

      &quot; If not, recommend one dedent
	let curind = curind - shiftwidth()
    else
      &quot; Otherwise, trust the user
      return -1

&quot;  endif

  &quot; If the previous line opened a block
  elseif getline(plnum) =~ '^\s*\(for\|if\|else\|elseif\|case\|while\|switch\|try\|otherwise\|catch\)\&gt;'
    &quot; See if the user has already indented

  &quot; If we got to here, it means that the user takes the standardversion, so we return it
