[PATCH] Better support for multiline expressions

[cboos]

Since r231, one can write multiline full expressions, i.e.

This complex value: ${...
 ... 
...}

However, this doesn't match well with Python syntax which doesn't tolerate white space in front of an expression (wrong indentation level issue).

As I can't think of any instance where this leading space may actually be expected or valid, I propose to simply left strip the white space on expressions, thereby making multiline expressions even easier and cleaner to write.

This complex value: ${
   ...
   ... # compute the value
   ...}

Trivial patch:

Yeah, good idea. Thanks!
