Weird, and doesn’t really match the commit log.  Maybe this hunk can be
removed?

Please prepend “XXX” here to make the kludge more visible.  (Eventually
we should fix it in Guile.)

I tried adding an @itemize list in a description and noticed that the
initial indent is not working the way I thought:

--8<---------------cut here---------------start------------->8---
$ ./pre-inst-env guix package --show=emacs-let-alist
name: emacs-let-alist
version: 1.0.4
outputs: out
systems: x86_64-linux i686-linux armhf-linux mips64el-linux
dependencies: emacs-no-x-24.5
location: gnu/packages/emacs.scm:491:2

synopsis: Easily let-bind values of an assoc-list by their names
description: This package offers a single Emacs Lisp macro, `let-alist'.  This
+ macro takes a first argument, whose value must be an alist (association list),
+ and a body.
+ 
+ des* iption: one
+ 
+ des* iption: two
+ 
+ des* iption: three
+ 
+ description: The macro expands to a let form containing the body, where each
+ dotted symbol inside body is let-bound to their cdrs in the alist.  Only those
+ present in the body are let-bound and this search is done at compile time.
--8<---------------cut here---------------end--------------->8---

Notice how “description:” is repeated for each @item and for the next
paragraph.

I wonder if using ‘fill-paragraph’ instead of ‘fill-string’ would solve
this.

Could you look into it?

Sorry for not noticing earlier!

Thanks,
Ludo’.
