Incorrect translations of gsettings schema key's localised default value

[Christian Persch <chpe gnome org>]

Hi;

gnome-terminal contains a gsettings schema with a value that allows
localising the default:

#: ../src/org.gnome.Terminal.gschema.xml.h:1
msgctxt "visible-name"
msgid "'Unnamed'"
msgstr ""

Here, the single-quotes around the string are essential, and *must* be
reproduced in the translated string, since this value will be parsed
as a GVariant of type "s" (string).

However, I've found out that many translations of this (msgctxt, msgid)
are using locale-specific quotes here, e.g.:

ca.po:msgctxt "visible-name"
ca.po-msgid "'Unnamed'"
ca.po-msgstr "«Sense nom»"

This will *not* work as intended, since parsing will fail and thus the
untranslated default value will be used (and a warning printed on
console).

At least the following translations are affected (but everyone else is
invited to double-check theirs too):

bg, ca, ca valencia, de, es, fr, gl, hu, ko, lt, lv, nb, ne, nl, sk,
sr, sr latin, te, zh_CN, zh_HK, zh_TW

Note that the same problem may also exist in other modules that use
translatable default values, but I didn't check for that.

Regards,
