Surely the straight thing to say is:

   >>> foo.replace(' CONTENT_PATH ', ' Substitute ')
   'foo bar baz spam Substitute bar spam'

But there was no guarantee of spaces around the target. If you wish to,
say, replace "spam" in your foo with "REDACTED" but leave it intact in
"May the spammer be prosecuted", a regex might be attractive after all.
