Sorry for the sequential posts, but I found the following contruct in
the same patch to be quite untranslatable.

> errmsg("%s bound of partition \"%s\" is %s %s bound of split partition",

I might be misunderstanding this, but if the expressions are correct,
the message could be divided into four fixed messages based on "first"
and "defaultPart". Alternatively, it might be better to provide
simpler explation of the situation.
