v14i008: Patch for pc2unix

Archive-name: pc2unix/patch01

There is a bug (or perhaps rather a misfeature) in pc2unix.c: If the input file
doesn't have a EOF marker (ASCII 26), it includes an extra ASCII 255 in the
output. Below is a patch to correct this (apply by extracting pc2unix.patch and 
then doing patch <pc2unix.patch). Hope this hasn't caused too much inconvenience.
