Lintian tag information: misnamed-po-file (type: warning)

Description (from lintian-explain-tags)

The name of this PO file doesn't appear to be a valid language code. Any
files in debian/po ending in .po will be processed as translations by
po2debconf for the language code equal to the file name without the
trailing .po. If the file name does not correctly reflect the language of
the translation, the translation will not be accessible to users of that
language.

If this file isn't actually a PO file, rename it to something that doesn't
end in .po or move it to another directory so that translation merging
programs will not be confused.

Visibility: warning
