sent when a sequence of calls to the function are made.

+The argument was added in Exim version 4.90 - changing the API/ABI.

Strings that are written by &'smtp_printf()'& from within &[local_scan()]&
JH/45 local_scan API: documented the current smtp_printf() call. This changed
for version 4.90 - adding a "more data" boolean to the arguments.
+ Bumped the ABI version number also, this having been missed previously;
+ release versions 4.90 to 4.92.3 inclusive were effectively broken in
+ respect of usage of smtp_printf() by either local_scan code or libraries
+ accessed via the ${dlfunc } expansion item. Both will need coding
+ adjustment for any calls to smtp_printf() to match the new function
+ signature; a FALSE value for the new argument is always safe.
