I found an old patch in my local worktree closely related to this work;
here we take the additional step of changing the pattern used for .snap
file names in logical decoding to use %X/%08X as the other patterns we
changed for this.  This changes both the sscanf() part of it as well as
sprinft().

Any objections against this?
