This is an extremely bad idea.  Legacy Bourne shell code from the
1980s kind of bad -- from the horrible days before we *had* arrays
in shells.  How are you going to handle filenames with spaces in them?
With newlines in them?  With commas in them?  With colons in them?  Tabs?
DEL characters?  Those are all valid in filenames.  Any delimiter you
can *put* in a shell string is also a valid character in a filename (or
at least in a pathname, which eliminates the possibility of using slash).
