Yeah, thinking more on this one using for this file different
permissions than the log files makes little sense, so what you propose
here seems like a sensible thing to do things. Even if we exclude the
file from native BASE_BACKUP this would not solve the case of custom
backup solutions doing their own copy of things, when they rely on
group-read permissions. This would not solve completely the problem
anyway if log files are in the data folder, but it would address the
case where the log files are in an absolute path out of the data
folder.

I am adding in CC Gilles who implemented current_logfiles for his
input.
