php concatenation unknown to xgettext

[Jan Engelhardt]

Hello,


the following minimal php source is not correctly parsed by xgettext:

        <?php
        _("foo"."bar");
        ?>

ran through `xgettext -o /dev/stdout test.php` gives:

        msgid "foo"
        msgstr ""

expected result:

        msgid "foobar"
        msgstr ""

The dot is the concatenation operator and is very handy when dealing 
with longer strings (esp when they take up more than 80 columns).


$ xgettext --version
xgettext (GNU gettext-tools) 0.15



Thanks,
        Jan
