Spell checking does not work with context

[Aditya Mahajan]

Hi,

 I am using vim 7.0 on windows and spell checking does not work with 
context files. (syntax file dated 2006-04-19)

 Here is a quick test.

1. start vim with
gvim -u NONE -U NONE

2. set the following options
syntax on
set syntax=context
set spell

3. Type the following
\starttext
This is a mistaake in typinng
\stoptext

The spell errors are not highlighted. If I change the syntax to 
plaintex

set syntax=plaintex

then syntax highlighting works.

Any idea what is wrong with context syntax files?

Thanks,
Aditya
