Adding while and until to the list of start block keywords in the parser

[camertron]

Currently while and until aren't identified as keywords by the haml parser.

I’m not sure this is needed – while and until don’t have anything like elsif or rescue like if and begin do (at least not as far as I know), so managing the indentation and adding the final end is straightforward. Do you have any test cases where this is causing problems? Perhaps we just need better names and comments in the code to explain what’s happening.

I was having trouble identifying when a bit of code needed an end statement when walking a haml parse tree. Perhaps you could explain how the haml gem does it? I think the only thing this change does is set the keyword variable in ParseNode instances, so it's pretty benign even if it's not strictly necessary.

We need test cases for this. What you expect for templates including those keywords is not clear. Please add them.

And since it has conflicts and passed 2-3 years, closing for now. Please reopen this if you still have this problem.
