s/more/less/, I think, was the original motivation.  Having to limit
more tightly than usual was what made the "config" unusual among
files under $GIT_DIR.  If it were to loosen, Eric's change should
not have been done in the first place. The sharedRepository setting
to defeat the default umask is there for that kind of thing.

It is merely an annoyance, to the same degree of annoyance we find
when we see all files appear executable on a FAT floppy mounted on
Linux ;-)  I do not think it is a risk at all, and I do not see a
point in going into people's repository and actively "fixing" it.
People who notice can fix, and people who do not care do not care
and are not harmed.
