[bug-gettext] msguniq fails on a duplicate empty msgid

[Raphaël]

If the body of a po file contains an empty msgid, msguniq will fail.

Sample a.po file; notice the empty msgid (commented "Y"):
> msgid ""
> msgstr ""
> "Language-Team: A\n"
> "MIME-Version: 1.0\n"
> "Content-Type: text/plain; charset=UTF-8\n"
> "Content-Transfer-Encoding: 8bit\n"
>
> #: X
> msgid "Unspecified error"
> msgstr ""
>
> #: Y
> msgid ""
> msgstr ""
>
> #: Z, dup of X
> msgid "Unspecified error"
> msgstr ""


Now run:
$ LANG=C msguniq -d /tmp/a.po 

> /tmp/a.po: warning: Charset missing in header.
>                     Message conversion to user's charset will not work.
> /tmp/a.po:13: duplicate message definition...
> /tmp/a.po:2: ...this is the location of the first definition
> msguniq: found 1 fatal error

IHMO this is a bug.
If you remove or comment empty msgid and msgstr of "Y", then msguniq will 
succeed.

Using Gentoo's gettext 0.18.1.1-r3
