Bug#600688: [patch] Retain langp when re-using buffer

[Bram Moolenaar]

James -

> Patch 7.2.034 introduced a bug which causes spell highlighting not to
> work when an empty buffer gets re-used when a file is loaded.  A simple
> test case is:
> 
>   $ vim -u NONE -N -c 'syn on' -c 'set spell'
>   :e src/os_win32.c
> 
> As you can see, none of the unknown words are highlighted as spelling
> mistakes although they are if you give the file on the command line
> instead.

> The attached patch looks like the right fix.

Thanks.  I'll check it out soon.
