org-macs: Fix indentation for full-width characters
* lisp/org-macs.el (org-do-remove-indentation): Handle full-width characters.
When the least indented line in buffer begins from fullwidth character
like 'あ', a Japanese character, `org-do-remove-indentation' doesn't
remove indentation at all or removes improperly.
e.g. 'あ' with 2 spaces indent
-----[buffer begin]-----
あ
-----[buffer end]-----
`org-do-remove-indentation' does nothing in this buffer.
Expected result is:
-----[buffer begin]-----
あ
-----[buffer end]-----
