bug#15501: 24.3; usage of read-passwd within format-alist

Indeed, read-passwd now relies on after-change-functions to hide the
password characters, but format-insert-file binds
inhibit-modification-hooks before calling the function found in
format-alist.

I installed a patch (see below) which should fix this issue, but I'm
curious: what do you use format-alist for that triggered this problem?
