So, the following are fixed now:

#155843

translations of attributes are not merged in XML files if tag itself needs no translation

#137029

non-interface strings from script-fu scripts get included in the script-fu po file

#48489

handle gettext escapes other than '\\' and '\"'

#155294

handle comments in Glade files

I've done a patch for another bug, but it might need more testing. It would be great if someone built entire Gnome with such patched intltool-merge, just as a stress-test (though, changes are simple, so I doubt anything will be wrong).

#145017

intltool-merge --pass-through causes problems in entity_encode

Additionally, I closed the bug which has been fixed for a while already:

#45501

should support xml:lang style of localization for merging (for gnumeric, Nautilus themes, etc.)

Yay for intltool bugs and bug fixing. ;-) ]]>
