Fix GCC 7 snprintf() compiler warning.

Browse Source 
Make buffer 1 byte larger to fit a sign.  It's actually impossible for
there to be a sign in practice, but this is still required to keep GCC 7
happy.

Cleanup from commit 51bc271790eb234a1ba4d14d3e6530f70de92ab5.

Based on a suggestion from Peter Eisentraut.
