The homedir is initially created with these permissions and I thought
it being a good idea to stay that way.  This way files that reside
into the directory, such as secring are inaccessible to group/others.
Anyway, because someone can add (--secret-keyring) a secring that's not
in the homedir I could write a function that checks perms of certain
important files.

Also, in the patch I sent the function that checks permissions is called a
little early.  It should reside 45 lines forward in the g10.c source file, in
order to use a possible --homedir argument.

Suggestions/comments?
