 Hi,
 
 Although removing the limit from sh(1) is probably not a bad idea It
 doesn't help people using older releases or other operating systems.
 (At least NetBSD has the same 79 character limitation.)
 
 Here's a patch for shar(1) which limits the EOF marker length to maximum
 of 79 characters. If the marker would be longer then we use simply
 "END-of-file" as marker.
 
 I don't think that this code would be too complex to add.
