Yup, the change looks fine to me, and the password change functionality
appears to work just fine for the open-document password.

There is one minor issue.  The dialog that gets launched from the Change
Password button also contains the optional password input for modifying
document, and setting a new password there doesn't appear to change the
modify-document password.  Not sure if this is worth fixing, or trivial
to fix...

I think the place where you put it is just fine for me.

Indeed.  I tried to git am your patch on master and it failed to apply.
I wonder if this is a big change, or just a minor change enough to make
the patch not apply cleanly...  I haven't looked too closely into it
yet.
