I don't think that's an issue anymore.

Ok, yeah, that's what I thought.  Sequence files are opened with
lkfopen() in sbr/seq_save.c.  Looks like that is an nmh thing; it's not
part of MH.  And it's been that way since ... forever, it seems.  It
predates us putting nmh into CVS, so I guess Richard Coleman did that.
Looking at things ... I guess he really rototilled the sequence code.
But it looks like the man page was never updated.
