My mistake, dryice is tied to uglify too much - it uses uglify's
Abstract Syntax Tree to walk the code and find 'require("module")'.
I cannot make that optional without cutting dryice legs.

On the other hand, uglifyjs2 only needs source-map for the cases where
one uses --source-map, something that is not used by source-map (pardon
the tautology).

I'll push this evening a patch on the master-experimental branch of uglifyjs,
just tell me if that's not right.

Jérémy.
