Message splits

Hi all

I find it useful to have the "Message splits" in the sendsms response body.
However, this is not appended in the trunk version of Kannel,
unless immediate-sendsms-reply = true. This has obvious disadvantages (less
sanity checking).

Would the maintainers be receptive to a patch that appends " Message
splits: %d" to the response body when:

concatenation = true
immediate-sendsms-reply = false

Or, if modifying the response body would be considered an unacceptable
compatibility breaker, would an HTTP response header be acceptable?

Thanks
Doug
