Command used to create a conflict-free .po file during merge.
The following parameters are provided by the hook:
``this`` is the ``.po`` file content before the merge in the current branch,
``other`` is the ``.po`` file content in the branch merged from,
``pot_file`` is the path to the ``.pot`` file corresponding to the ``.po``
file being merged.
``result`` is the path where ``msgmerge`` will output its result. The hook will
use the content of this file to produce the resulting ``.po`` file.
All paths are absolute.
