[patch] window title not being updated when doing ":language fr_FR.UTF-8"

[Dominique Pellé]

Hi

I see a minor bug in Vim-7.3.329 on Linux.
Command ":language fr_FR.UTF-8"  does not update the language
of the title in the terminal or title of gvim. Doing ":redraw!" does not
help either.  The language of the title gets updated after resizing the
terminal or gvim.

Steps to reproduce:

1) Start gvim with:
    $ (export LANG=en_US.UTF-8; gvim -u NONE -U NONE)

2) Observe that the window title is in English "[No Name] - GVIM1".

3) Enter Ex command    :language fr_FR.UTF-8

4) Observe that window title is still in English (bug!, I'd
   expect it to become in French).
   Doing ":redraw!"  does not work around.
   Observe that after resizing the window, title then
   becomes in French:  "[Aucun nom] - GVIM1"

Attached patch fixes it.

Regards
-- Dominique
