After the update to gettext 0.23, the AppStream metainfo XML files generated
by msgfmt are invalid if a translation is available for the 'ca@valencia'
language. The output from appstreamcli validate:

E: @appid@:79: tag-duplicated name (lang=ca)
   This tag must only appear once in this context. Having multiple tags of
this kind is not valid.

E: @appid@:162: tag-duplicated summary (lang=ca)
   This tag must only appear once in this context. Having multiple tags of
this kind is not valid.


Steps to reproduce:

git clone https://gitlab.gnome.org/GNOME/nautilus.git
msgfmt --xml --template nautilus/data/org.gnome.Nautilus.metainfo.xml.in.in -d
nautilus/po -o org.gnome.Nautilus.metainfo.xml
appstreamcli validate --explain org.gnome.Nautilus.metainfo.xml


The problem is caused by this commit:
https://git.savannah.gnu.org/gitweb/?p=gettext.git;a=commit;h=446241c7cabb9b5de52c63248aa2574ce1acb388

It seems that the value 'ca@valencia' is transcoded into 'ca', and if 'ca' is
already present, it causes duplicated <name xml:lang="ca"> tags.
