[PATCH] lisp/org.el (org-set-tags): Calculate width of tags with string-width

[Yasushi SHOJI <yashi@atmark-techno.com>]

* lisp/org.el (org-set-tags): Width of strings presenting on a buffer
should be calculated with `string-width' instead of `length'.

This fixes unaligned tags for the languages with multi-width
characters.
---
Hi,

I just noticed that tags are not aligned when I use Japanese chars for
tags.  This patch should fix it.

Other two usages of `length' in the function are fine since they seem
to be used to find the length of lists.

oh, I also found one trailing white space in the fine.  Please drop
that hunk if you don't want to mix it.

Best,
