It's kind of crude that do_pg_stop_backup() has to parse the
backuplabel with sscanf() when it's coming from a non-exclusive backup
- we could pass the location as a parameter instead, to make it
cleaner. There might be a point to it being the same in both
codepaths, but I'm not sure it's that important...
Doesn't this code put the backup label in *every* tarfile, and not
just the main one? From what I can tell the code in
SendBackupDirectory() relies on labelfile being NULL in tar files for
"other tablespaces", but the caller never sets this.
Finally, I'd move the addition of the labelfile to it's own function,
but that's just me ;)
