I'm running MH.6 on a 4.2bsd system.

When are holes in the msg list (because rmm'd msgs), scan would
sometimes complain about not being able to open one of these nonexistant
msgs.  In one case, "folder -pack" complained and quit after trying to
compact the msg list.

Below is the fix to sbr/m_gmsg.c
