Documentation @errtext[]

There are other collections of error codes which I don't think @ERRTEXT handles, for example, COM errors, typically 0x8XXXXXXX. While there are larger ones <=15999, this is the biggest one @ERRTEXT reports on here (Win7).
v:\> echo %@errtext[15301]
The hash requested from the server is not available or no longer valid.
So for Windows 7 - errtext[0..15301] would be good. thanks. I think I will just do something like this:

for /l %n in (0,1,16000) (echo %@errtext[%n] > "%@format[05,%n]_err.txt")
as some are multiple lines.
