I also think it makes a lot of sense to handle permissions centrally.

However, with this patch, the permissions of the target file will
additionally be limited by umask (by passing them to open()), and then
overridden completely if core.sharedRepository is set.

Perhaps the lockfile API should respect the location of the lock files
(i.e. use core.sharedRepository in .git, 0666 in the work-tree, and
copy permissions anywhere else).

Another thing I find strange is that, by doing copy/replace, git silently
overwrites readonly files. If we grab the permissions from the source
file anyway, we should perhaps add 'if (!(perms & 0222)) error("file
is readonly");', or even 'access(filename, W_OK)'?
