Below.

> Subject: [PATCH] Input methods for Urdu, Pashto and Sindhi
> 
> * lisp/leim/quail/pakistan.el (quail):
> ("urdu-keyboard"): new input method
> ("urdu-phonetic-keyboard"): new input method
> ("urdu-custom"): new input method
> ("sindhi-keyboard"): new input method
> ("pashto-keyboard"): new input method

These should be brought together, and the description should start
with a capitalized letter and end with a period.  Like this:

 * lisp/leim/quail/pakistan.el ("urdu-keyboard")
 ("urdu-phonetic-keyboard", "urdu-custom", "sindhi-keyboard")
 ("pashto-keyboard"): New input methods

> ; (pakistan--define-quail-rules): helper function
> ; (pakistan--make-setter): helper function
> ; (pakistan--regenerate-translations): helper function
> ; (pakistan--set-prefixes): helper function
> ; (pakistan--set-numeral-translations):

Why are there semi-colons here?

> (pakistan-urdu-input): new customization group
> (pakistan-urdu-prefixes): new custom variable
> (pakistan-urdu-translations): new custom variable
> (pakistan-urdu-diacritics-and-other-symbols): new custom var
> (pakistan-urdu-poetic-symbols): new custom var
> (pakistan-urdu-religious-symbols): new custom var
> (pakistan-extra-balochi-brahui-translations): new custom var
> (pakistan-extra-pashto-translations): new custom var
> (pakistan-extra-sindhi-translations): new custom var
> (pakistan-extra-saraiki-hindko-translations): new custom var
> (pakistan-urdu-use-roman-digits): new custom var
> (pakistan): new package

This should again be a single entry about multiple variables, since
they all share the same description: "New custom variable".

While compiling this, I get byte-compiler warnings:
