unzip: fullFileName to: pathString
"Unzip the contents of the file specified by the full path name
fullFileName to the location given by pathString."
so we would expect to pass a string in the second argument?
the unique sender of it in the system
unzip: fullFileName
"Unzip the contents of a gzipped file specified by its full file
name to the current working directory"
^ self unzip: fullFileName to: FileSystem disk workingDirectory
but the implementation seems to indicate that fullFileName is should be
a string as well as pathString
unzip: fullFileName to: pathString
"Unzip the contents of the file specified by the full path name
fullFileName to the location given by pathString."

Am I correct to think that the comments are not really good enough?
