text/template: Raw quote doesn't allow \n

[gopherbot]

by jeffdh:

Raw quotes within a template cannot include '\n' which seems counter to the golang
syntax that does allow '\n'.

Here's an example:

http://play.golang.org/p/ZDIphkpwDh

What is the expected output?
The parser should allow the raw quote with the included '\n'

What do you see instead?
The parser fails thinking the raw quote is unterminated

Which version are you using?  (run 'go version')
First noticed in go1.2, but I see nothing has changed in tip.
I've attached a patch that addresses the issue and changes the test to match.

Comment 1:

The template language is not Go, however the lexical grammar might be similar. More
importantly, the documentation[0] explicitly states that:
""""
Actions may not span newlines, although comments can.
""""

Comment 2:

Also, http://play.golang.org/p/DJOeuHq7M7 is perhaps what you want.

I think, it would be useful to have multiline raw. I use swigjs on the frontend which has a very similar syntax and it would be nice to just wrap those blocks to not be processed. For now ive just changed the server's delimiter to work around this.
