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...
