Problem: shiftwidth() does not take 'vartabstop' into account.
Solution: Use the cursor position or a position explicitly passed.
Also make >> and << work better with 'vartabstop'. (Christian
Brabandt)
*<*
<{motion} Shift {motion} lines one 'shiftwidth' leftwards.
+ If the 'vartabstop' feature is enabled, and the
+ 'shiftwidth' option is set to zero, the amount of
+ indent is calculated at the first non-blank character
+ in the line.
*<<*
<< Shift [count] lines one 'shiftwidth' leftwards.

-shiftwidth([{list}]) *shiftwidth()*
+shiftwidth([{col}]) *shiftwidth()*
Returns the effective value of 'shiftwidth'. This is the
'shiftwidth' value unless it is zero, in which case it is the
'tabstop' value. This function was introduced with patch
- 7.3.694 in 2012, everybody should have it by now.
-
- When there is one argument {list} this is used as position
- |List| for which to return the 'shiftwidth' value (actually
- only the column number is relevant). This matters for the
- 'vartabstop' feature. For the {list} arguments see |cursor()|
- function. If the 'vartabstop' setting is enabled and no
- {list} argument is given, the current cursor position is
- taken into account.
+ 7.3.694 in 2012, everybody should have it by now (however it
+ did not allow for the optional {col} argument until 8.1.542).
+
+ When there is one argument {col} this is used as column number
+ for which to return the 'shiftwidth' value. This matters for the
+ 'vartabstop' feature. If the 'vartabstop' setting is enabled and
+ no {col} argument is given, column 1 will be assumed.
