Replace docbook commands like dbtimestamp with a placeholder in po(t) files
Docbook XML commands in po(t) files can be confusing for translators. They may not know that they should not be translated.
e.g. we have in src/gimp.xml:
<copyright>
<!-- TRANSLATORS: do not translate <?dbtimestamp format="Y"?> -->
<year>2002-<?dbtimestamp format="Y"?></year>
<holder>The GIMP Documentation Team</holder>
</copyright>
Converted to gimp.pot:
#. TRANSLATORS: do not translate <?dbtimestamp format="Y"?>
#: src/gimp.xml:30(year)
msgid "2002-<?dbtimestamp format=\"Y\"?>"
msgstr ""
If possible, we should look into replacing that inside our xml2po parser with a <placeholder/>
like we already do for certain other cases.
