[ Upstream commit ffff7ee843c351ce71d6e0d52f0f20bea35e18c9 ]
This corrects an out-by-one error in the maximum length of the package version string. The size argument of snprintf includes space for the trailing '\0' byte, so there is no need to allow extra space for it by reducing the value of the size argument by 1.
Found by inspection. Compile tested only.
