Thanks.  This still has a few issues, though.

First, when I try to activate the pashto-keyboard input method in
"emacs -Q", Emacs signals en error:

  Symbol’s value as variable is void: pakistan-urdu-use-roman-digits

I wonder how this worked for you.

Each defcustom should have a :version tag stating the first version in
which it will appear.
