imap-append.c example: incorrect pointer check in payload_source()

[achuykov]

Hi,

This condition is always true because even incorrect offset produces valid (non-NULL) pointer:
data = &payload_text[upload_ctx->bytes_read];
if(data) {

I expect that "if" condition should check the end end of ASCIIZ string:
if(*data) {

Thanks,
Alexander

Yes, makes perfect sense!
