Respect whitespace in feature descriptions

[mattwynne]

We've just added a feature to relishapp[1] which passes each Feature's description through a markdown formatter.

The problem I've hit is that gherkin seems to be stripping the whitespace which I'd have expected to be left at the start and end of lines in the description. Whitespace is quite important for markdown formatting: you need to add two spaces to the end of the line to make it write a <br/> tag, and you're probably familiar with four space indents for pre-formatted blocks.

I've added a failing scenario in my fork of gherkin[2] but I'll need some help making it pass, assuming that it's possible and you guys think it's a good idea.

To save you having to run it, the feature fails with:

-    "description" => "one line  \nanother line\n    some pre-formatted stuff",
+    "description" => "one line\nanother line\n\nsome pre-formatted stuff",
         "keyword" => "Feature",
            "line" => 1,
            "name" => "Foo"

I've got this working with the Ruby lexer, but it's going to take some infinite monkey business to get the C lexer working. Any volunteers to help?

Good work on this folks - I just released 2.3.2 which has this fix.
