Ah, sorry, I was confused.  Again.  Ouch.

Please let me try to summarize the situation to make sure that I
understand it.  We're talking about two different patches, either of
which you say will solve the problem.  The January patch is:

--- a/lib/localcharset.c
+++ b/lib/localcharset.c
@@ -262,6 +262,7 @@ get_charset_aliases (void)

and the July patch is:

If I understand things correctly, you're saying the January patch is
more logical, but that either will work, and so you'd settle for
either.

Bruno has objected to the January patch, but has not commented on the
July patch.  You've responded to Bruno's January objections, and he
hasn't had time to follow up.

Thanks for mentioning that.  By "the proposed fix" I assume you mean
the January patch.

I'd greatly appreciate Bruno's comments, if he has the time.  If not,
I'm thinking of pushing the July patch, as a temporary fix until Bruno
does find the time, since he hasn't objected.
