A few weeks ago, someone posted a "joiner" script to combine the various parts
of a multipart BinHex posting.  I decided to give it a try on the Esperanto
stack posting that just went past and discovered a little (?) error.  It looks
for lines that start with three hyphens and does no other checking.  This can
and does happen in the middle of BinHexed files (witness part 10 of the
Esperanto stack), causing great foulups.  I have corrected it to look for lines
that start with three hyphens AND a space.  This cannot happen in the middle
of a BinHex run, since spaces aren't legal there.  The corrected script follows:

#! /bin/csh -f                                            
# usage: joiner file > joined                              
#   or  cat parts | joiner > joined                    
                                                        
if ($#argv == 0) then                                  
        sed -n -e '/^--- /,/^--- /  p' | sed -e '/^--- / d'
else                                                     
        sed -n -e '/^--- /,/^--- /  p' $1 | sed -e '/^--- / d'
endif                                                   


I hope that this will be of help to others.  I normally wouldn't even have
seen it as I have MPW scripts to do this sort of thing, but just decided to let
the Pyramid have a go at it.
