Hello Guix, The Texinfo manual says [0] that I should be able to use @abbr, and prefer it over @acronym when the text is not all capital letters, but I get a backtrace when I try to use it in a package description: --8<---------------cut here---------------start------------->8--- Backtrace: In ice-9/boot-9.scm: 1752:10 16 (with-exception-handler _ _ #:unwind? _ # _) In unknown file: 15 (apply-smob/0 #) In ice-9/boot-9.scm: 724:2 14 (call-with-prompt _ _ #) In ice-9/eval.scm: 619:8 13 (_ #(#(#))) In guix/ui.scm: 2185:7 12 (run-guix . _) 2148:10 11 (run-guix-command _ . _) In ice-9/boot-9.scm: 1752:10 10 (with-exception-handler _ _ #:unwind? _ # _) In guix/scripts/package.scm: 906:9 9 (_) In srfi/srfi-1.scm: 634:9 8 (for-each # ?)
