shiftwidth() function documentation error

2014-10-09 Fir de Conversatie Benjamin Fritz
shiftwidth() *shiftwidth()*
Returns the effective value of 'shiftwidth'. This is the
'shiftwidth' value unless it is zero, in which case it is the
'tabstop' value.  To be backwards compatible in indent
plugins, use this: 
if exists('*shiftwidth')
  func s:sw()
return shiftwidth()
  endfunc
else
  func s:sw()
return sw
  endfunc
endif
 And then use s:sw() instead of sw.

I think the else block should be:

else
  func s:sw()
return (sw ? sw : ts)
  endfunc
endif

If I recall correctly, before the shiftwidth() function was introduced, 
the value of 'shiftwidth' couldn't be zero. So the documentation is 
correct.

Best,
Christian
