glob will split the string you give it on whitespace, allowing you to use
such patterns as glob("*.h *.c"). When you don't remove the newline from
your input line, you sre giving glob the string "directory\n/*". This is
parsed into the two strings "directory" and "/*". The second of these will
expand to all of the files in your top-level directory.
See 'perldoc -f glob' and 'perldoc File::Glob'
