Using <TAB> in $code blocks causes IndentationError

[Daniel Hahler]

When using <TAB> to indent a $code block, webpy throws an IndentationError.

I'm attaching a file to reproduce this: start bug.py and request localhost:8080 in your webbrowser.

It should throw the following exception:
<type 'exceptions.IndentationError'> at /
unexpected indent Template traceback: File '<template>', line 7 None (<template>, line 7)

When changing the TAB in line 7 (which is actually line 11 in the file) to be indented using space (1 or 4 does not matter), it gets parsed as expected.

I'm using Git HEAD.
