Commit https://git.savannah.gnu.org/cgit/guix.git/commit/?id=b13b9384bc43bf93c754c037956c8ef9a99c2b41 causes a recent 'guix pull' to throw a parse-error:

texinfo.scm:745:27: Throw to key `parser-error' with args `(#<input: string 7f64e6483230> "EOF while reading a token " "reading char data")'

I believe this is due to missing trailing '}' in the en title:

 (entry (commit "49af34cfac89d384c46269bfd9388b2c73b1220a")
        (title (en "@command{guix pull} now honors
@file{/etc/guix/channels.scm")
                            ^

BTW, is there a good way to test these news entries, since they appear to be code and can cause errors for users like this?  './pre-inst-env guix pull --news' seems to still read news ~/.config/guix/current.
