Diet template does not support soft tab indent

[zhaopuming]

When using soft tab (2 spaces as a tab) with index.jd, like:

extends layout.jd
block body
  h1 Example page - Home
  p Hello, World!

vibe complains about

diet.d(137): Error: "Error in template index.jd line 3: Inside an extension template, only 'block' tags are allowed at root level.(diet.d:169)"

I think its because diet does not recognize soft tab as an indent and regards h1 Example ... as a new block, hence the error.

Should that be supported? I found that jade-lang.org are using soft tab in there examples

My idea was to avoid the problems you can get with mixed tabs/spaces by just allowing tabs. But you made me think that maybe detecting the type of indentation (tabs or N spaces) at the first indented line would be a good alternative. All following lines would then be forced to use the same indentation style.

Yes, detecting indentation by the first indented line, it's exactly what I wanted :) Python syntax does this too

This is now implemented with d7ac37b.
