Clean up buffer wrapping method
Remove extraneous punctuation

It turns out that in Coffeescript (and perhaps JavaScript as well)
that when passing an object to a function, the braces are not required
around the object. Additionally, the quotes are not required around the
property names. Removed both.
Remove requirement to not have copyright

Since I changed the insert copyright command to insert the text at the
current location, checking to see if there is a copyright notice at the
top of the file is a little lame. Assuming the user knows what they're
doing.
