Whitespace collapsing is dangerous

[rutsky]

When using Dojo declarative syntax for writing methods developer can write inline JavaScript comments, e.g.:

<script type="dojo/method" data-dojo-event="getChildren" data-dojo-args="object">
     // Supply a getChildren() method to store for the data model where
     // children objects point to their parent (aka relational model)
     return this.query({parent: this.getIdentity(object)});
</script>

(full example at http://livedocs.dojotoolkit.org/dijit/Tree-examples#id3 )

When spaces are being collapsed, such multiline code becomes single line of commented code, e.g.

<script [...]> // Supply [...] // children [...] return this.query({parent: this.getIdentity(object)}); </script>

which may lead to runtime errors about undefined variables (since now function doesn't return anything).

Spaces should be collapsed in smarter way taking in account such Dojo features.
