People tend to save snippets like that in files of notes and use them
later out of context by cut-n-paste.  My use of >> was just paranoia.
If later someone decides to use that line to add another key to the
file (after all, that is how they added the first key) then it won't
overwrite their file at that later time and possibly lock themselves
out of a system.
