Same applies to git-archive, which generates files with mode 666 and
directories with 777, while it could follow the modes in the
repository... or at least, that's what the manpage claims, but facts
seem to be quite different...

mh@namakemono:~/git/git$ umask
0022

And no value is set for umask in git config...

I also never understood why there were no permissions set on directories
in trees... nor why, while the sha1 for child objects are "packed", the
modes aren't...
