Just had another idea: maybe make the new variable names
SERVER_VERSION_SSERVER_VERSION_NVERSION_SVERSION_N

"_S" could usefully be read as either "string" or "short", and probably
we should document it as meaning "short".  This way avoids creating any
weird inconsistencies with the existing precedent of the VERSION variable.
