Sorry but I don't know what you mean with "translations that flow
from RTL e.g. ".siht od t'nod :tnih"." so I can't check this.
As far as I can see the callers only put a simple message in it,
e.g. advise(_("Commit your changes or stash them to proceed."));
So I don't think that this patch would break anything.
