Re: [Nmh-workers] Relative Message Numbers

Minor nit; your character set was "utf8", but technically it's supposed
to be "utf-8" (with the dash).  Ralph also might be getting this wrong,
I keep meaning to mention that.  Anyway ...

Hm.  I'm torn.  So, it looks like it's okay in terms of syntax; "_" is
not a valid character in a sequence.  But what are the semantics if
“name” refers to more than one message?
