[bug#50144] [PATCH] doc: Work around po4a doc generation hangup.

[Sergei Trofimovich <slyich@gmail.com>]

Multiple people are affected by 'guix pull' hangup.
The reproducer is:

    $ po4a-translate -d -M UTF-8 -L UTF-8 -k 0 -f texinfo \
      -m "doc/guix.texi" -p "po/doc/guix-manual.de.po" -l "doc/guix.de.texi.tmp"

The regression is bisected down to commit fc29c80b9
("guix: opam: More flexibility in the importer").

The workaround is to avoid multiline @code{...} directive.

* doc/guix.texi: Avoid multiline @code{...} directive.
