patch for po-edit-string in po-mode

[Kenichi Handa]

Hi, attached is a patch to fix a small problem of
po-edit-string.  Currently it creates an edit-buffer without
explicitly setting a major mode.  So, functions in
after-change-major-mode-hook doesn't run in that buffer.

This is a reply from a maintainer of Emacs

I think it's not, tho it's obviously a misfeature.  I think the best
answer is to say that a buffer that is intended to be displayed to the
user should call a major-mode function.  If there's no specific
major-mode for it, it should call fundamental-mode.
------------------------------------------------------------

The better will be to make a real major-mode (say,
po-subedit-mode) that inherits most features from text-mode.
